A solid block ‘A’ wéighing ‘Q’ kg is resting on flat floor. A smooth cylinder ‘B’ weighing ‘P’ kg. is placed betweenthe solid A and the vertical wall as shownin fig. The friction between the cylinder, wail and the block A is negligible. The co-efficient of friction between the block A and floor is $$\mu$$ The minimum weight P required to disturb the block A is

A

$$\frac{Q(1 - \tan \theta)}{\mu \tan \theta}$$

B

$$\frac{\mu Q \tan \theta}{(1 - \mu \tan \theta)}$$

C

$$\mu Q \cos \theta$$

D

$$\frac{\mu Q}{\cos \theta}$$
