You've been invited to try out a new hoversuit, and here's how it works: Someone has set up a large flat sheet, many kilometers across, somewhere on the Earth, and they've charged the sheet up to a uniform charge density of 9.95 x 10^-6 C. You are issued a special suit that you wear, and it has controls on it which allow you to charge the suit up to any number of Coulombs (C), positive or negative, that you might want. The idea is that you can control the amount of electrical repulsion (or attraction) between the suit and the charged sheet below you.  Suppose your mass (including the suit) is 67.1 kg. How much charge must you give the suit if you want to be able to just hover stationary above the charged sheet?     7.02E-04 C     1.76E-03 C     1.87E-03 C     1.17E-03 C

Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.
