In the figure shown, a cubical block is ...

In the figure shown, a cubical block is held stationary against a rough wall by applying a force F, then. Incorrect statement among the following is :

A

Frictional force f = Mg

B

F = N, N is normal reaction

C

F does not apply any torque about C.M.

D

N does not apply any torque about C.M.

Text Solution

Verified by Experts

The correct Answer is:
D
To keep rotational equilibrium N should not pass through C.M. so it's torque about C.M. is not zero
