GSHSEB Class 12 Physics Question Bank Solutions

Preparing for Class 12 Physics requires a clear understanding of concepts, formulas and their applications. Students often find it challenging to solve MCQs and numerical problems involving electrostatics, magnetism, current electricity and electromagnetic induction. Practising questions from the question bank can help students understand important concepts and become familiar with different question patterns.

The GSHSEB Class 12 Physics Question Bank Solutions provide question-based revision of important topics from the Gujarat Board syllabus. It covers MCQs, conceptual questions, formula applications, and numerical problems. Students can use the explanations to understand the reasoning behind each answer, revise important formulas, and identify concepts that need further practice.

Class 12 Physics Question Bank Solutions Overview

The GSHSEB Class 12 Physics question bank revision covers important concepts from different chapters. It includes questions on electric dipoles, electric potential, electrostatic shielding, capacitance, current electricity, magnetic fields and electromagnetic induction.

Students can also revise dimensional analysis, magnetic properties of materials, inductors, electric flux and circuit-related calculations. It focuses on solving MCQs by applying the correct concepts and formulas rather than memorising answers. This approach supports revision for school unit tests and helps students practise different types of Physics questions.

Important Topics Covered in GSHSEB Class 12 Physics Question Bank

The question bank solution covers several important Physics concepts through objective questions and numerical applications.

1. Electric Dipole and Electrostatics

Questions on electric dipoles explain the behaviour of a dipole placed in a uniform electric field. Students learn that the net force on an electric dipole in a uniform electric field is zero because the forces on its two charges are equal and opposite. However, the dipole may experience torque depending on the angle between its dipole moment and the electric field.

The section also covers charged soap bubbles, electric potential at axial and equatorial positions of a dipole, electric fields and electrostatic shielding. Students revise why the electric field inside a conductor in electrostatic equilibrium is zero.

2. Magnetism and Magnetic Properties of Materials

It includes questions on magnetic fields produced by current-carrying conductors and loops. Students revise the interaction between two parallel wires carrying currents in opposite directions and understand the relationship between current direction and magnetic force.

It also covers the magnetic properties of materials, including diamagnetism. Water is discussed as an example of a diamagnetic substance, which is weakly repelled by an external magnetic field. Other concepts include the magnetic moment of a bar magnet and the behaviour of hollow cylindrical conductors.

3. Electromagnetic Induction and Inductance

Electromagnetic induction questions focus on the relationship between induced electromotive force and the rate of change of magnetic flux. Students understand how the speed of a moving magnet affects the induced EMF in a coil.

It also explains the difference between induced EMF and induced charge. The total induced charge depends on the change in magnetic flux and the resistance of the circuit. Questions on choke coils and inductors help students revise the energy stored in an inductor using the formula.

4. Capacitance and Electric Potential

The question bank includes problems on equivalent capacitance when capacitors are connected in parallel. Students also practise questions involving charged conducting shells, electric potential and Coulomb's law.

Other important concepts include electric flux through a cube when a charge is placed on its surface and the effect of a dielectric medium on electric force. It also explains the interpretation of a voltage-charge (V-Q) graph, where the area under the graph represents the energy stored in a capacitor.

5. Current Electricity and Electrical Circuits

Current electricity questions involve calculating the EMF and internal resistance of a cell. Students also revise the condition for maximum power transfer and practise interpreting current-voltage graphs at different temperatures.

The section includes circuit problems involving galvanometers and resistance. These questions help students understand electrical measurements, circuit behaviour and the application of relevant formulas.

6. Dimensional Analysis and Important Units

Dimensional analysis is another important area covered in the question bank. Students practise questions involving electric potential, resistance, magnetic permeability, magnetic flux, inductance and the torsional constant of a galvanometer.

These questions help students understand dimensional formulas and check the consistency of physical equations. Revising SI units and dimensional expressions can also support accuracy in objective questions.

7. Magnetic Force and Motion of Charged Particles

It covers questions involving protons, deuterons and alpha particles moving perpendicular to a magnetic field with equal kinetic energy. Students revise the relationship between the radius of a charged particle's circular path, its mass, charge, velocity and the magnetic field.

Other questions include the time period of a magnet oscillating in a magnetic field and the application of magnetic force concepts to moving charged particles.

How to Prepare for GSHSEB Class 12 Physics Unit Tests
