Asmall piece of dust has a mass of 3.1 * 10^-3 kg and a charge of -33 µc. it is placed at a certain spot where there is an electric field. when released, the object experiences an acceleration of 2.25 *10^3 m/s^2 in the direction of the +x axis. determine the magnitude and direction of the electric field.

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.
