Q. For a hypothetical hydrogen like atom, the potential energy of the system is given by $\text{U} \left(\text{r}\right) = \frac{- \left(\text{Ke}\right)^{2}}{\left(\text{r}\right)^{3}}$ , 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 :
