2 protons, each with charge q=1.602E-19 C, are fixed in space. They form a spherical nucleus with diameter 1E-15 m. An electron with charge q=-1.602E-19 C is in circular orbit around the nucleus with radius 6E-11 m.
1. Find electric potential for the electrons orbit?
2. Find electric potential energy for the electron in orbit?
3. Find total energy of the electron in orbit?
