A positively charged particle is released from rest in an unifrom electric field . The electric potential energy of the charge

Question

$\begin{array}{1 1} \text{remains a constant because the electric field is uniform } \\ \text{increases because the charge moves along the electric field } \\ \text{decreases because the charge moves along the electric field} \\ \text{decreases because the charge moves opposite to the electric field } \end{array}$
