Problem

Two point charges,

+3\,\mu\text{C}

and

-5\,\mu\text{C}

, are fixed

0.20\,\text{m}

apart on the

x

-axis. The

+3\,\mu\text{C}

charge is at the origin and the

-5\,\mu\text{C}

charge is at

x = +0.20\,\text{m}

. Which statement best describes the direction of the electric force exerted on the

+3\,\mu\text{C}

charge? a) There is no net force on the

+3\,\mu\text{C}

charge because the two charges have different magnitudes b) Toward the

+x

direction, that is, toward the

-5\,\mu\text{C}

charge c) Toward the

-x

direction, that is, away from the

-5\,\mu\text{C}

charge d) Along the

+y

direction, perpendicular to the line joining the charges
