Problem

A small metal sphere carrying a charge of

+6.0\,\text{nC}

touches an identical neutral sphere that is insulated from its surroundings. After the spheres are separated, the first sphere is measured to have

+2.0\,\text{nC}

. What is the net charge on the second sphere? a)

-4.0\,\text{nC}

+2.0\,\text{nC}

+4.0\,\text{nC}

0\,\text{nC}
