Q. 93.8( 4 Votes )

A person says that he measured the acceleration of a particle to be nonzero while no force was acting on the particle.
A. He is a liar.

B. His clock might have run slow.

C. His meter scale might have been longer than the standard.

D. He might have used non-inertial frame

Class 11th HC Verma - Concepts of Physics Part 1 5. Newton’s Laws of Motion

Answer :

If no force is acting on the particle, then it can be seen accelerating only from an accelerated frame which is a non-inertial frame.

Thus, option D is correct.

When a body slides down from rest along a smooth inclined plane making an angle of 45° with the horizontal, it takes time T. When the same body slides down from rest along a rough inclined plane making the same angle and through the same distance, it is seen to take time pT, where p is some number greater than 1. Calculate the co-efficient of friction between the body and the rough plane.
