. Suppose the potential energy between electron and proton at a

distance r is given by -ke²/3r³ Application of Bohr’s theory to hydrogen atom in this case shows that

A. energy in the nth orbit is proportional to n⁶

B. energy is proportional to m^–6 (m : mass of electron)

C. Energy in the nth orbit is proportional to n^–2

D. energy is proportional to m³ (m = mass of electron)
