# A charge accelerating between two plates

Hi all,

Suppose an alpha particle of 3.2 x 10-19 C accelerates from rest between two oppositely charged plates starting from the positive plate. The electric field between the plates is uniform equal to 39000N/C. The distance between the plates is 4.50 x 10-3m

Does the alpha particle potential energy change? I assume since the field is uniform then the PE will not change.
