Each of the two block shown in the figure has mass m. The pulley is smooth and the coefficient of friction for all surfaces in contact is `mu`. A constant horizontal force `P` applied in two cases shown in such a way that block A start just sliding then the value of minimum force `P` in case-I and case-II is :

A cubical block of side .L. rests on a rough horizontal surface with coefficient of friction mu . A horizontal force F is applied on the block as shown in figure. The minimum force required to topple the block is

A cubical block of side L rests on a rough horizontal surface with coefficient of friction mu . A horizontal force F is applied on the block as shown. If the coefficient of frictions sufficienty high so that the block does not slide before toppling, the minimum force required to topple the block is : .
