Question

The driver in a vehicle moving with a constant speed on a straight road is in a non-inertial frame of reference. A reference frame in which Newton?? laws of motion are applicable is non-inertial.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (C)

If assertion is true but reason is false

Answer 2

If we take a body resting with respect to two frames with origin $O$ and $O^{\prime}$ then the body will be at rest. But the frame (vehicle) is moving with constant speed, so, this frame can not be an inertial frame of reference or it is a non inertial frame of reference. But the frame in which Newton's law of motion are applicable is an inertial frame.
