For a hypothetical hydrogen like atom, the potential energy of the system is given by `U(r)=(-Ke^(2))/(r^(3))`, where r is the distance between the two particles. If Bohr's model of quantization of angular momentum is applicable then velocity of particle is given by:

Options

A. `v=(n^(2)h^(3))/(Ke^(2)8pi^(3)m^(2))`
B. `v=(n^(3)h^(3))/(8Ke^(2)pi^(3)m^(2))`
C. `v=(n^(3)h^(3))/(24Ke^(2)pi^(3)m^(2))`
D. `v=(n^(2)h^(3))/(24Ke^(2)pi^(3)m^(2))`
