In which case does an electric field do positive work on a charged particle?
A negative charge moves opposite to the direction of the electric field.
A positive charge is moved to a point of higher potential energy.
A positive charge completes one circular path around a stationary positive charge.
A positive charge completes one elliptical path around a stationary positive charge.
If the distance between two isolated parallel plates that are oppositely charged is doubled, the electric field between the plates is essentially unchanged. However, the:

force on a charged particle halfway between the plates will get twice as small.
potential difference between the plates will double.
force on a charged particle halfway between the plates will get four times as small.
