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
