(b)

Answer to Problem 86P
No, the charge imbalance explain Earth’s orbit.
Explanation of Solution
Consider the charge of electron and proton is different. The net charges on astronomical bodies are the sum of charge of the particles. If the magnitude of the charges of the proton and electron were not exactly equal, astronomical bodies will have a total charge with the same sign.
Like charges will repel each other. Since the charges of the astronomical bodies are similar, the force between them would be repulsive. The force responsible for the Earth’s orbit is attractive. Thus, the charge imbalance explain Earth’s orbit.
