Question

Newtons law are not valid in

• A. Both inertial as well as non- inertial frame of reference.
• B. A frame moving with constant velocity w.r.t. an inertial frame.
• C. All reference frames which are at rest w.r.t. an inertial frame.
• D. The reference frame attached to the earth.

Answer 1

The correct option is A Both inertial as well as non- inertial frame of reference.

Newton's Law is only valid in inertial frame of reference. If there is a non - inertial frame of reference then it won't be valid.

Hence option $\text{A}$ is the correct answer.
