A parallel-plate capacitor has charge Q and -Q on its plates. One half of the gap between the two plates is filled with uniform dielectric with permittivityand the other half is filled with air as shown in the figure. What is the relation between the electric field E0 in the air and E in the dielectric?
A、E0>E.
B、E0<e.<br> C、E0=E.
D、Indeterminable.
