A test charge of +3 µC is at a point P where the electric field due to other charges is directed to the right and has a magnitude of 4 x 106 N/C. If the test charge is replaced with a charge of -3 µC, the electric field at P:
(a) has the same magnitude as before, but changes direction
(b) increases in magnitude and changes direction
(c) remains the same
(d) decreases in magnitude and changes in direction
