q_(2) is the following:
(a) positive
|q_(2)| =
(b) negative
|q_(2)| =
as the distance between q and the spot P. With q present, the magnitude of the net electric field at P is twice what it is when q is present alone. Given that q = +3.25 C, determine the magnitude |q| when q is the following:
(a) positive 1q1 = [
(b) negative 1q1 = |
