Electric Potential in the Middle of Two Point Charges

EANDM-RBVYYL

Two equal point charges $Q=3.5 \: \text {nC}$ are spaced a distance $L=10 \: \text{cm}$ apart.

What is the electric potential, $V_T$, at the midway point along a line between the two charges? Assume that the potential is zero at infinity.

A

$V_T = 0 \: \text V$

B

$V_T = 1260 \: \text V$

C

$V_T = 630 \: \text V$

D

$V_T = 12 \: \text V$

E

$V_T = 314 \: \text V$
