Problem

Two fixed point charges are kept on the x-axis:

+3\,\mu\text{C}

x = 0

and

+8\,\mu\text{C}

x = 50\,\text{cm}

. At what point on the line joining them should a charge of

+1\,\mu\text{C}

be placed so that it experiences zero net electrostatic force? Give your answer as the distance from the origin.
