(a) Assume you place equal numbers of excess electrons on the Earth and on a satellite of mass 1600 kg which is in a circular orbit around Earth at a distance 38000 km from the center of the Earth. How many such electrons would you need to place on each body in order that the repulsive electrical force between them would cancel the attractive gravitational force between them? number of electrons in the satellite ? electrons. (b) Suppose the spacecraft is made of aluminum (atomic mass 30, atomic number 13); calculate the electrons. What fraction of excess electrons does the satellite need to have: (The fraction for the Earth would be much smaller.)
