MCQ
Newtons law are not valid in:
  • 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

Correct option: 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.
