Passage-I :
A hollow cube of side L has two parallel sides conducting and remaining four sides are non conducting. It is filled with a liquid of dielectric constant K. A small hole of area A at bottom of cube is open at t = 0 and liquid starts leaking throught it. The two conducting sides are connected by a battery of emf E `(L=9m A=(18)/(sqrt(20))m^(2)k=10 E=81v, g=10m//sec)`
