Imagine that 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 3.92 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 81.2 kg. How much charge must you give the suit if you want to fall up , that is, accelerate upward at the same rate that objects normally accelerate downward due to Earth s gravity? 7.19E-03 C 2.16E-03 C 1.01E-02 C 1.15E-02C
