The electric potential energy of the charge 0.027 J.
The electric potential of a charge is the work done in moving the charge from infinity to a certain distance in the electric field.
V = qEd
where;
V = 4.5 x 10⁻⁵ 2 x 10⁴ x 0.03
V = 0.027 J
Thus, the electric potential energy of the charge 0.027 J.
