Homework Help: Physics

Posted by Susan on Sunday, January 13, 2008 at 10:26pm.

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?

F=kqq/d^2

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.
