Solve The Following Questions of NCERT Solutions for Class 12 Maths Chapter 10 Exercise 10.1:
Question 1. Represent graphically a displacement of 40 km, 30° east of north. Solution : Displacement 40 km, 30° East of NorthNCERT Solutions for Class 12 Maths Chapter 10 Exercise 10.2
Question 2. Check the following measures as scalars and vectors: (i) 10 kg (ii) 2 meters north-west (iii) 40° (iv) 40 Watt (v) 10 –19 coulomb (vi) 20 m/sec 2 Solution : (i) 10 kg is a measure of mass, it has no direction, it is magnitude only and therefore it is a scalar. (ii) 2 meters North-West us a measure of velocity. It has magnitude and direction both and hence it is a vector. (iii) 40° is a measure of angle. It has no direction, it has magnitude only. Therefore it is a scalar. (iv) 40 Watt is a measure of power. It has no direction, only magnitude and therefore, it is a scalar. (v) 10 –19 coulomb is a measure of electric charge and it has magnitude only, therefore, it is a scalar. (vi) 20 m/sec 2 is a measure of acceleration. It is a measure of rate of change of velocity, therefore, it is a vector. Question 3. Classify the following as scalar and vector quantities: (i) time period (ii) distance (iii) force (iv) velocity (v) work done Solution : (i) Time-scalar (ii) Distance-scalar (iii) Force-vector (iv) Velocity-vector (v) Work done-scalarNCERT Solutions for Class 12 Maths Chapter 10 Exercise 10.3
