Two Conducting Spheres Find The Weight Of The Spheres Physics - Two Identical Conducting Small Spheres Are Placed?

Physics - two identical conducting small spheres are placed? - two conducting spheres find the weight of the spheres

Two identical small spheres are to be borne with their centers to be located 300 meters away. It receives a surcharge of 12 UC and the other has a load 18uC. a) Determine the magnitude and direction of the electric force between the two areas. b) Find the electric field strength and direction when the two spheres are connected by a cable. (Note: If the distribution of the burden?)
