Suppose that the negative charge in a copper one-cent coin were removed to a very large distance from Earth-perhaps to a distant galaxy-and that the positive charge were distributed uniformly over Earth's surface. By how much would the electric potential at the surface change? (By taking the mass of a penny to be 3.11 g, the positive or negative charge is found to be 1.37×105 C)
