Question
A dielectric slab of thickness d is inserted in a parallel plate capacitor whose negative plate is at x = 0 and positive plate is at x = 3d. The slab is equidistant from the plates. The capacitor is given some charge. As one goes from 0 to 3d(a) The magnitude of the electric field remains the same(b) The direction of the electric field remains the same(c) The electric potential increases continuously(d) b, c
