There is an object, which 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 one. The co–efficient of friction between the body and the rough plane is
- 1/p
- µ = (1 − 1/p2)
- 1/p2
- 2 − p
Answer
(B) µ = (1 − 1/ p 2 )
