1.) Find the acceleration of gravity at the surface of a planet as a function of its radius and average density. Do not use mass in the formula.
2.) Using the results from part 1.), what would the surface gravity of Jupiter be if it had the same average density as Earth?
How does this compare with the actual surface gravity of Jupiter?
Two facing surfaces of two large parallel conducting plates separated by 11.5 cm have uniform surface charge densities such that are equal in magnitude but opposite in sign. The dissimilarity in potential among the plates is 600 V.
