Question

An electron and a proton attract eachother with a 1/ r2 electric force, just like thegravitational force. Suppose that an electron moves in a circularorbit about a proton with a period of the circular motion of 2.06hr. What is the radius of the orbit? An electron and a proton attract eachother with a 1/ r2 electric force, just like thegravitational force. Suppose that an electron moves in a circularorbit about a proton with a period of the circular motion of 2.06hr. What is the radius of the orbit?

Explanation / Answer

    The radius of the orbit is                r = [(GmpT2)/(42)]1/3 Here mp = 1.67*10-27 kg             G = 6.67*10-11 N.m2/kg2              T = 64964160 s              Substitute the values for r.              Substitute the values for r.
