When a block moves down a smooth inclined plane of inclination 
, its velocity on reaching the bottom is v. When it slides down a rough inclined plane of same inclination, its velocity on reaching the bottom is v/n, where n is a number greater than 1. The coefficient of friction between the block and the rough surface is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
For smooth incline, v 2 = 2 (g sin 
) 
s ......(l)
For rough incline, 
.... (2)
On solving (1) and (2), we obtain,
