RRB ALP Science Previous Year Questions

RRB ALP Science Previous Year Questions cover important Physics, Chemistry, Biology, and General Science concepts through exam-oriented MCQs that help candidates understand frequently asked topics and improve their preparation.

Question 1: Dispersion of Light

Q. Which of the following is responsible for the dispersion of white light through a glass prism?

• (a) The prism absorbs some colors.

• (b) Different colors of light travel at different speeds in glass.

• (c) White light contains only one color.

• (d) Different colors of light travel at the same speed in glass.

Question 2: Fleming's Rules

Q. Fleming’s left-hand rule is used to determine the direction of motion in an electric motor. Which finger represents the direction of force or motion?

• (a) Thumb

• (b) Forefinger

• (c) Little finger

• (d) Middle finger

Question 3: Kinetic Energy

Q. When the velocity of a body is doubled from its original value, its kinetic energy becomes:

• (a) Four times the original value

• (b) Half of the original value

• (c) Same as before

• (d) Double of the original value

Note: Since Kinetic Energy (KE) = 1/2 × m × v², doubling the velocity (2v) results in 2² = 4 times the kinetic energy. 

Question 4: Solutions and Stability

Q. When is a solution called stable?

• (a) When solute particles float on the surface of the solution when left undisturbed.

• (b) When solute particles settle down when left undisturbed.

• (c) When solute particles form a separate layer with solvent particles.

• (d) When solute particles do not settle down when left undisturbed.

Question 5: Chemical Equations

Q. Consider the unbalanced reaction:

C2H6 + O2 -> CO2 + H2O 

Which of the following is the correct set of coefficients to balance this equation?

• (a) 1, 5, 3, 4

• (b) 2, 7, 4, 6

• (c) 2, 5, 4, 6

• (d) 1, 3, 2, 3

Question 6: Laws of Motion

Q. A person is standing in a bus that suddenly stops. The person falls forward. Which of the following laws of motion is directly responsible for this phenomenon?

• (a) Newton’s second law of motion.

• (b) Law of conservation of momentum.

• (c) Newton’s first law of motion.

• (d) Newton’s third law of motion.

Question 7: Plant Reproduction

Q. New plants can arise from the roots of which of the following plants?

• (a) Maize

• (b) Sweet potato

• (c) Potato

• (d) Gram

Question 8: Evolutionary Biology

Q. Why is variation in a population of organisms mainly important?

• (a) It increases the chances of survival in changing environmental conditions.

• (b) It ensures that all individuals are identical.

• (c) It always gives immediate results within the same generation.

• (d) It helps organisms reproduce faster.

Question 9: Agricultural Practices

Q. Which of the following is an example of growing two or more crops simultaneously on the same land area in a definite pattern?

• (a) Aeroponics

• (b) Hydroponics

• (c) Intercropping

• (d) Monocropping

Question 10: Cell Biology

Q. Due to the presence of which particles does rough endoplasmic reticulum (RER) appear rough under the microscope?

• (a) Centrosomes

• (b) Ribosomes

• (c) Lysosomes

• (d) Peroxisomes

Question 11: Electrochemistry

Q. What is used as the anode during electrolytic refining?

• (a) A rod of graphite

• (b) A strip of impure metal to be refined

• (c) An inert electrode

• (d) A strip of pure metal to be refined
