An alpha particle with charge +2.0 e is sent at high speed toward a copper nucleus with charge +29 e. What is the electric force acting on the alpha particle when the alpha parti- cle is 1.5 x 10 m from the copper nu- cleus? The value of the Coulomb constant is 8.99 x 109 N·m²/C2. 14 Х m

explanation:

could i give you a exaplo that could you?

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.

i will answer your question if you answer mine

force tends to be low and long diustance masses are high
