A solid cube is placed on a horizontal surface. The coefficient of friction between them is `mu=0.25`. A variable horizontal force is applied on the cube’s upper face, perpendicular to one edge and passing through the mid-point of edge, as shown in figure. The maximum acceleration with which it can move without toppling is (take `g=10m//s^(2)` )

Text Solution

Verified by Experts

The correct Answer is:
5
`mu mg xx (l//2)+P xx (l//2)=mg(l//2)`
`P=mg-mu mg and P-mu mg=ma`
hence `a=g(1-2mu)=5`
