Problem

Two identical small conducting spheres are isolated in air. One sphere carries a charge of

+8\,\mu\text{C}

, and the other carries

-2\,\mu\text{C}

. The spheres are briefly touched together and then separated. What is the final charge on each sphere? (a)

+5\,\mu\text{C}

on each sphere (b)

+6\,\mu\text{C}

on the sphere that was originally positive and

0\,\mu\text{C}

on the other (c)

+3\,\mu\text{C}

on each sphere (d)

+6\,\mu\text{C}

on each sphere
