How many electrons are on each sphere if the resultant force is 4500 N? Enter the email address you signed up with and we'll email you a reset link. Since balls 2 and 3 repel each Being made of metal (a conductor), electrons are free to move between the spheres - from sphere A to sphere B and vice versa . Two identical metal spheres have charges +15C and +25C areseparated by a distance. The distance between them is x and angle between the threads (2= 10). After bringing them in contact with each other, they again placed at the same distance apart. Two uncharged conducting spheres, A and B, are suspended from insulating threads so that they touch each other. (b) A positively charged glass rod is brought near the sphere on the left, attracting negative charge and leaving the other sphere positively charged. Now, here we will derive the formulas related to this equilibrium condition. the other sphere has no net charge.
