Question 5

An air-filled parallel-plate capacitor is connected to a source of emf. The electric field has a strength of $E\,$ between the plates. While the capacitor remains connected to the source of emf, the separation between the plates is halved.

What is the final electric field strength between the plates?

A

$4 E$

B

$2 E$

C

$E$

D

$E2\frac{E}{2}$
