Problem

A point charge of

+6\,\mu\text{C}

is fixed at the origin. A second point charge of unknown magnitude

q

is fixed on the

x

-axis at

x=0.20\,\text{m}

. Determine the value of

q

required so that the electric potential at the point

x=0.10\,\text{m}

is zero. (a)

-12\,\mu\text{C}

(b)

+6\,\mu\text{C}

(c)

-6\,\mu\text{C}

(d)

-3\,\mu\text{C}
