Electric force on electron in hydrogen atom with unknown charges

[pete1667]

Electric Force!

I am uncertain how to apply Coulomb's law, if this is even the right way to go about it, to this problem on Electric Force because I am not given two charges. The question is: On average, the electron and proton in a hydrogen atom are separated by a distance of 5.3x10^-11 m. Assuming the orbit of the electron to be circular, (a) what is the electric force on the electron? () What is the electron's orbital speed? (c) What is the magnitude of the electron's centripetal acceleration in units of q?Thank you for your help

Of course you are given two charges. Both the proton and electron are charged particles. (They have the same magnitude of charge, but different signs; look up the charge on the electron.)

What is the equation for the Columb force? What is the equation for centriptal acceleration in uniform circular motion?
