A 5.0-C charge is 10 m from a small test charge. What is the magnitude of the electric field at the location of the test charge?
4.5 x 10⁹ N/C.
4.5 x 10⁸ N/C.
4.5 x 10⁶ N/C.
4.5 x 10⁷ N/C.
Two charged objects attract each other with a certain force. If the charges on both objects are doubled with no change in separation, the force between them:
Two charged objects are separated by a distance d. The first charge is larger in magnitude than the second charge.
