Homework Help: Physics

The hydrogen atom contains a proton, mass 1.67 10-27 kg, and an electron, mass 9.11 10-31 kg. The average distance between them is 5.3 10-11 m. The charge of the proton is the same size, opposite sign of the electron.

a)What is the magnitude of the average electrostatic attraction between them?


You would have to convert from kg to C, correct? Then, plug everything into the formula.

b)What is the magnitude of the average gravitational attraction between them?

I am drawing a complete blank on the formula for this one and I cannot find it in my notes.
