A point X is located equidistant from point A (q+) and B (q-) in a parallel plane.(adsbygoogle = window.adsbygoogle || []).push({});

If the field intensity of A(q+) at point X is E, then what would the new field intensity be if point B (Q-) is added?

A) 2E

B) 0

C) 1/2E

D) 3/4 E

I assumed the answer is 2E, since the field of the positive charge (A) plus the field of the negative charge (B) are combined, however, my friend says it's B and I'm not sure anymore. Please, help?
