We will now derive the formula for the change in electric potential energy of a charged object q in a constant electric field E when the charged object is moved with displacement Ax. (Please refer to Fig. 1) FAx (Equation 1) F = qE (Equation 2) = -W (Equation 3) W APEetec Substituting Eq. 1 in Eq. 3, APEetec = -FAx (Equation 4) Then subs. Eq. 2 in Eq. 4, APE etec = -qEAx (Eq. 2.1) Which is what we need to derive.
