4) There are two charges q1 = 35 μC and q2 = 50 μC placed 0.5 m apart and fixed in place. Where should the charge q3 = 15 μC be placed so that it experiences no force on it?

5) Suppose Earth and the Moon each carried a net negative charge −Q. Approximate both bodies as point masses and point charges. (a) What value of Q is required to balance the gravitational attraction between Earth and the Moon? (b) Does the distance between Earth and the Moon affect your answer? Explain. (c) How many electrons would be needed to produce this charge?
