Two metal spheres, each of radius 25.0 mm, have a center-to-center separation of 3.00 m. Sphere 1 has charge 2.00 × 10−8 C; sphere 2 has charge -4.00 × 10−8 C. Assume that the separation is large enough for us to say that the charge on each sphere is uniformly distributed (the spheres do not affect each other). With V = 0 at infinity, calculate the potential at point #1.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
