## Homework Statement

Two parallel conducting plates, separated by a distance d, are connected to a battery of emf $$\epsilon$$. Which of the following is correct if the plate separation is doubled while the battery remains connected?
a. The electric charge on the plates is doubled.
b. The electric charge on the plates is halved.
c. The potential difference between the plates is doubled.
d. The potential difference between the plates is halved
e. The capacitance is unchanged.

## Homework Equations

$$\Delta$$V = $$\epsilon$$ - Ir

## The Attempt at a Solution

I'd actually appreciate it if someone could explain this question to me. I'm having some difficulty with these concepts. What exactly is the question asking? I can probably take it from there.
