As shown in figure the horizontal surface of block M 0 is smooth and its vertical surface is rough with a coefficient of friction µ. Then –
A
If F = 0 the blocks cannot remain stationary
B
For F = 
, blocks m 1 and m 2 remain stationary with respect to M 0
, blocks m 1 and m 2 remain stationary with respect to M 0
C
For F = 
, blocks m 1 and m 2 remain stationary with respect to M 0
, blocks m 1 and m 2 remain stationary with respect to M 0
D
The limiting friction between m 2 and M 0 is independent of F
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(a, b, c)
Observe in reference frame attached to M 0
a = 
(B, C) Pseudo = m 1 a = m 2 g ± µm 2 a, for no relative motion
f l.s. = µm 2 a
