A test charge of +3 µC is at a point P where the net electric field due to other charges is directed to the right and has a magnitude of 4 106 N/C. If the test charge is replaced with a charge of -3 µC, what happens to the electric field at P?

The field has the same magnitude as before, but changes direction.

The field remains the same.

The field decreases in magnitude and changes direction.

The field increases in magnitude and changes direction.
