Consider the situation shown in figure. Suppose a small electric field E exists in the space in the vertically upward direction and the upper block carries  a positive charge Q on its top surface. The friction coefficient between the two blocks is `mu` but teh floor is smooth. what maximum horizontal force F can be applied without disturbing the equilibrium?
