Rotational MotionHard
Question
An equilateral prism of mass m rests on a rough horizontal surface with coefficient of friction μ. A horizontal force F is applied on the prism as shown in the figure. If the coefficient of friction is sufficiently high so that the prism does not slide before toppling, then the minimum force required to topple the prism is -
Options
A.
B.
C.
D.
Solution
The prism will be topple when the torque due to F becomes greater than the torque of weight about the front corner of the prism.
∴
∴ F = 
∴
∴ F = Create a free account to view solution
