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 1.11 x 10^-6 C/m2. 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. What is the strength of the electric field in the region above the charged sheet? (This is easy, since I m going to give you the formula, which is E = 2 pi k Q/A, where k is the electrical constant and Q/A is the charge density.)

QUESTION 10
Suppose you were hovering stationary as in question 6 above, except now with sheet charge density 3.56 x 10^-6 C and your mass including
the suit 84.7 kg. Suppose that while you were hovering, someone threw you a rock of mass 5.3 kg, and that you caught it. What would now
be your rate of acceleration toward the ground?
0.58 m/s^2
9.81 m/s^2
9.23 m/s^2
0.70 m/s^2
