Homework Help: Physics

Posted by Leslie on Friday, November 9, 2012 at 6:44am.

In a Bohr of a Hydrogen atom, an electron moves in a circle with a radius of 5.10(^-9) cm around a nucleus charged positive due to electrostatic force. What is the intensity of the force so that the electron has a velocity of 2.3 x 10(^8) cm/s? The mass of the electron is 9x10(^-28)g.




I tried to break this problem down into components using F=ma and a=vt, but I could get nowhere. Thank you to anyone who could break down the steps and help!
