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) )

A 3 kg block is placed over a 10 kg block and both are palced on a smooth horizontal surface. The coefficient of friction between the block is 0.2 . If a horizontal force of 20 N is applied to 3 kg block, accelerations of the two block in ms^(-2) are (take, g=ms^(-2) )

A cubical box of side length L rests on a rough horizontal surface having coefficient of friction mu . A variable horizontal force F=alpha t is applied on the top of the block as shown in figure, where alpha is a constant and t is time. The coefficient of friction is sufficient so that the block does not slide before toppling. The graph between torque due to normal reaction about end B and time before toppling start is
