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

A uniform cube of mass M and side a is placed on a frictionless horizontal surface. A vertical force F is applied to the edge as shown in figure. Match the Column I with Column II and mark the correct choice from the given codes.

	Column-I		Column-II
(i)	$\frac{Mg}{4} < F < \frac{Mg}{2}$	(p)	Cube will move up
(ii)	$F > \frac{Mg}{2}$	(q)	Cube will not exhibit motion
(iii)	F > Mg	r)	Cube will begin to rotate and slip at,4.
(iv)	$F = \frac{Mg}{4}$	(s)	Normal reaction effectively at $\frac{a}{3}$ from A, no motion
