In the situation shown in figure a wedge of mass m is placed on a rough surface, on which a block of equal mass is placed on the inclined plane of wedge.Friction coefficient between plane and the block and the ground and the wedge `(mu)`. An external force F is applied horizontally on the wedge. Given the m does not slide on incline due to its weight. The value of F at which wedge will start slipping is:

Options

A. `=mumg`
B. `=((3)/(2))mumg`
C. `gt2mumg`
D. `ltmumg`

Answer

C

Explanation

Wedge will start slipping when `Fgemu(2mg)`
