What is the net charge on the balloon

Reference no: EM13560574

You rub an inflated balloon on the carpet andit acquires a potential that is 1500 V lower than its potential before it became charged. If thecharge is uniformly distributed over the surface of the balloon andif the radius of the balloon is 13.0 cm what is the net charge on the balloon?
