# Four point charges form a square with sides of length d, as shown in the figure.

Four point charges form a square with sides of length d, as shown in the figure. In the questions that follow, use the constant k in place of $\frac{1}{4\pi {ϵ}_{0}}$.

Part A
What is the electric potential ${V}_{\to t}$ at the center of the square?
Make the usual assumption that the potential tends to zero far away from a charge.
${V}_{\to t}=$
Part B
What is the contribution ${U}_{2q}$ to the electric potential energy of the system, due to interactions involving the charge 2q ?
${U}_{2q}=$
Part C
What is the total electric potential energy ${U}_{\to t}$ of this system of charges? Express your answer in terms of q, d, and appropriate constants.
${U}_{\to t}=$
, plz i want just the final answers , thanks
