Please find the solution in the attachment.
Phsyical science Book Bill W.Tillery 8th edition ( need shown steps taken to produce the correct answer)
1. An inflated rubber balloon is rubbed with a wool cloth until an excess of a billion electrons is on the balloon. What is the magnitude of the charge on the balloon?
Ans. Charge on an electron = 1.6 x 10¬-19
Total Charge = number of entities multiplied by charge on ...
Rate of energy and other concepts are studied and discussed in the solution.
