A block moves down a smooth inclined plane of inclinationθ. Its velocity on reaching the bottom isv. If it slides down a rough inclined plane of same inclination, its velocity on reaching the bottom isv / n, wherenis a number greater than 1. The coefficient of friction is given by

Options:

Answer:
A
Solution:

For smooth, v2=2g sinθ s . . .(1)

For rough, vn2= 2 g sinθ-μcosθS. . .(2)

on solving, μ=1-1n2tanθ
