Spheres A and B have the same initial positive charge. The magnitude of the repulsive electric force between the two spheres is 144 N when separated by a distance of 0.03 m. (a) Find the initial charge . (b) The spheres are then allowed to touch each other and then separated. Find the electric force between them if the radius of sphere A is three times that of sphere B. What is the magnitude and direction of the electric field at 0.25 m from a ? Find the flux through the top, left, and right sides of a cube of side 0.5 m when placed in a horizontal uniform electric field of 8.0 N/C directed to the right.
