Problem

Two point charges of

+2\,\mu\text{C}

and

-3\,\mu\text{C}

are kept

10\,\text{cm}

apart in air. If the

-3\,\mu\text{C}

charge is replaced by a

+3\,\mu\text{C}

charge while keeping everything else the same, how will the electrostatic interaction change? a) Magnitude remains the same; force is still attractive b) Magnitude becomes three times; force becomes repulsive c) Magnitude remains the same; force becomes repulsive d) Magnitude becomes three times; force remains attractive
