Two charges of equal magnitude are placed at opposite corners of a square, as shown in the diagram above.

What is the magnitude of the net electric potential at point P, which is located at a third corner of the square?

A

0

B

$\cfrac { 2k{ Q } }{ { L } }$

C

$\cfrac { k{ Q } }{ { \sqrt { 2 } L } }$

D

$\cfrac { \sqrt { 2 } k{ Q } }{ { L } }$
