Electric Field of Two Charges 2

APPHEM-RSI4V4

The diagram shows two equal charges q isolated from other sources of charge, along with a point A that forms an isosceles right triangle with the charges. Note the signs of the charges shown.

What is the direction, if any, of the electric field at point A due to these two charges?

A
B
C
D
E

None, since E = 0 at point A.
