Can someone help me with this problem: Consider a simplified model of the singly-ionized helium atom, He+: 2 protons plus 2 neutrons in the nucleus, "orbited" by one electron at a constant distance of 2.65 x 10^-11m. a. What is the magnitude of the attractive electrostatic force between the nucleus and electron? b. What is the magnitude of the attractive gravitational force between the same two particles? I know I have to use Coloumbs Law, but I'm wondering if I have to just plug in numbers. How do I start? How do I get Q1 and Q2? Thanks!
