Physics - Current Electricity Question with Solution | TestHub

A non-relativistic particle of mass $m$ is held in a circular orbit around the origin by an attractive force. The potential energy of the force is given by $\mathrm{m}U(r)=\frac{k{r}^2}{2}$, where r is the distance of the particle from origin and k is a constant. Assuming the Bohr quantization of the angular momentum of the particle, choose the correct statement(s):

$(v\to$ velocity of particle, $KE(r)\to$ kinetic energy of particle, $E(r)\to$ total energy of the particle)
