Asteroid X orbits moon XYZ with a speed of 500 m/s and a centripetal force of 1500N. Asteroids X, Y and Z all have the same mass. i. If asteroid Y orbits moon XYZ with the same orbital radius as asteroid X but at a speed of 1000 m/s, what is the centripetal force acting on asteroid Y? ii. If asteroid Z orbits moon XYZ with a speed of 1500 m/s but on orbital radius that is half of asteroid X, what is the centripetal force acting on asteroid Z?

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

do you have a formula possibly

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.
