A dielectric slab of dielectric constant k mass m thickness

A dielectric slab of dielectric constant k mass m thickness d and area L x L is hanging vertically in equilibrium under the influence of gravity and electrostatic pull of a capacitor connected to a battery of voltage V The capacitor has plates of area L x L and distance between plates is d The capacitor is half filled by the dielectric Suddenly a mass of m is attached to dielectric without any impulse on the system The slab falls off in time t Evaluate t in sec Take k 2 V 4 volts L 80 cm d 0 1 mm
