Problem

Two positive point charges

+8\,\mu\text{C}

and

+2\,\mu\text{C}

are fixed

30\,\text{cm}

apart on a straight line. At what distance from the

+8\,\mu\text{C}

should a point be located (along the line joining the charges) so that the net electric field at that point is zero? a)

20\,\text{cm}

on the side of the

+2\,\mu\text{C}

away from the

+8\,\mu\text{C}

20\,\text{cm}

toward the

+2\,\mu\text{C}

24\,\text{cm}

toward the

+2\,\mu\text{C}

d) No such point exists
