if in Bohrs atomic model it is assumed that force between electron and proton varies inversely as r4 energy of the system will be proportional to? ? Share with your friends Share 9 Ved Prakash Lakhera answered this We know for electrons to move in the circular orbit aroud the nucleus of hydrogen atom, we have; mv2r=KZe2r4 since force α 1r4or K. E.=mv22=KZe22r3and P. E.=KZe2r4.dr=-4KZe2r5Therefore total energy =P. E. + K. E. =-4KZe2r5+KZe22r3OR E=KZe2-8r2+12r5Therefore energy E α 1r5 -103 View Full Answer
