On a very unrealistically staticky day, Zoey decides to try to hold up the weight of her body by grabbing onto a balloon she rubbed on her head. She rubs it on her head and then holds it up to the ceiling and lets the force of static electricity between the balloon and the ceiling hold her up. If Zoey weighs 700N and the charge on the balloon is 1.5 x 10-9 C and the balloon is 4.0 x 10 3 m away from the ceiling's charge, then what must the charge on the ceiling be to be able to create a force of electricity equal to Zoey's weight?

Problem 2: Space explorers discover an mA = 8.7 x 10¹7 kg asteroid that happens to have a positive charge of qA 4400 C. They would like to place their ms = 3.3 x 105 kg spaceship in orbit around the asteroid. Interestingly, the solar wind has given their spaceship a charge of qs = -1.2 C. What speed must their spaceship have to achieve a 7500-km- diameter circular orbit? qA, MA = + 2 9.gs, ms FIG. 3: The scheme for Problem 2 a) In Fig. 2, draw the vectors that represent the gravitational and electric forces experienced by the satellite. Compute the magnitudes of these forces. (Note: Do not use the formula |F| 9.8 ms 2, to compute the gravitational force, because that formula is valid only at low altitudes, and only for the gravitational field of the Earth. Instead, use Newton's law of gravity, F = Gmams, where G is the gravitational constant, and R is the radius of the orbit.) = msg, where g R²
