Given: g = 6.67259 × 10−11 n m2 /kg2
a 944 kg meteor comes in from outer space and impacts on the a moon’s surface (this moon is not necessarily the earth’s moon). the mass of this moon is m = 7 × 1022 kg, and the radius of this moon is r = 1.5 × 106 m. how much work is done by the moon’s gravitational field? answer in units of j.

Along the line connecting the two charges, at what distance from the charge q1 is the total electric field from the two charges zero? express your answer in terms of some or all of the variables s, q1, q2 and k =14ï€ïµ0. if your answer is difficult to enter, consider simplifying it, as it can be made relatively simple with some work.
