Physics · MOTION IN A STRAIGHT LINE

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The magnitude of instantaneous speed at an instant is equal to the magnitude of the instantaneous velocity at that instant. Reason (R): Speed is a scalar quantity while velocity is a vector quantity. In the light of the above statements, choose the correct answer from the options given below:

1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
3. (A) is true but (R) is false.
4. (A) is false but (R) is true.
