Question

Assertion : The driver in a vehicle moving with a constant speed on a straight road is in a non-inertial frame of reference.

Reason : A reference frame in which Newton's laws of motion are applicable is non-inertial.

(a) Both A and R are true and R is the correct explanation of A

(b) Both A and R are true but R is not correct explanation of A

(c) A is true but R is false

(d) A and R are false

Answer 1

Correct option (d) A and R are false

Explanation :

A frame is non-inertial if the particle in the frame does not move with a constant velocity. Here the driver moves with a constant speed on a straight road. It is therefore an inertial frame. The assertion is not true.

Newton's laws of motion are not applicable in case of non-inertial frame.

The reason is not true.
