For this question, once again consider a capacitor consisting of two metal plates separated by a distance d have charge +Q and -Q on the top and bottom plates, respectively, as shown below. d ++++ +Q E -Q This time assume that the separation distance between the two plates does not change, but instead a dielectric slab is inserted between the two plates. (a) Does the electric field E in the region between the plates increase, decrease, or remain the same after the slab is inserted? If E increases or decreases, by what factor does it increase or decrease? (b) Does the magnitude of the potential difference V between the top plate and bottom plate increase, decrease, or remain the same after the slab is inserted? If |V| increases or decreases, by what factor does it increase or decrease? (c) Does the capacitance C increase, decrease, or remain the same after the slab is inserted? If C increases or decreases, by what factor does it increase or decrease? (d) Does the energy stored in the capacitor increase increase, decrease, or remain the same after the slab is inserted? If the stored energy increases or decreases, by what factor does it increase or decrease?
