Suppose I had a large sphere with 10 protons and 10 neutrons. Another sphere with 2 protons and 2 electrons. How many different electrostatic forces would be acting between the two spheres? What would be the likely net force between the two spheres in this example? How would this change if I stripped 2 electrons away from the larger sphere?
The Attempt at a Solution
what do they mean by how many "different electrostatic forces"?
Would the net force be 0? and i don't think it would change even if i stripped away 2 electrons?
