When a body slides down from rest along a smooth inclined plane making an angle of `30^(@)` with the horizontal, it takes time 20s. When the same body slides down from rest along a rough inclined plane making the same angle and through the same distance, it takes time 20p is, where p is some number greater than 1. The coefficient of friction between the body and the rough plane is

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 coefficient of friction between the body and the rough plane.

A body slides down from rest along a smooth inclined plane making an angle of 45^(@) with the horizontal and takes time 'Y' to slide down the whole length of the plane. If the plane surface is rough the same body takes n.t time to slide down same length of the plane where n is a number greater than one. What is the value of coefficient of friction between the body and rough plane surface?

A body slides down in a time ‘f from rest along a smooth inclined plane making an angle of 45° with the horizontal. When the same body slides down from rest along a rough inclined plane of same length making the same angle, it takes time ‘pt then the coefficient of friction between the body and the rough plane is (p is a constant)

Starting from rest , a body slides down at 45^(@) inclined plane in twice the time it takes to slide down the same distance in the absence of friction. The coefficient of friction between the body and the inclined plane is
