Figure shows two parallel plates, R and S joined to a battery of voltage V and with charges +Q and –Q.

1. the energy stored is QV.
2. the electric field strength between the plates increases uniformly from S to R.
3. the electric potential between the plates decreases uniformly from R to S.

Which of the statement is/are correct?

3 only

The electric potential between the plates decreases uniformly from R to S.
