A parallel plate capacitor is half filled with a dielectric slab of dielectric constant (K) and mass M. Capacitor is connected to a cell of e.m.f. E. Plates are held fixed on horizontal surface. A bullet of mass M hits the dielectric elastically and it is found that the dielectric slab just leaves out the capacitor. Find the speed of the bullet?
