Question

An initially neutral electroscope is charged by induction bybringing near a positively charged object. If 3.32×108 electrons flowthrough the ground wire to Earth and the ground wire is thenremoved, what is the net charge on the electroscope?

Explanation / Answer

        No. of electronsremoved, n = 3.32 X 10 8         Net charge = n e                          = 3.32 X 10 8 * 1.6 X 10 -19                          = 5.296 X 10 - 11 C
