An electron is moving round the nucleus of a hydrogen atom in a circular orbit of radius r. The Coulomb force \(\vec{F}\) between the two is:
- \(-\kappa \frac{e^{3}}{r^{3}} \hat{r}\)
- \(\kappa \frac{e^{2}}{r^{3}} \vec{r}\)
- \(-\kappa \frac{e^{2}}{r^{3}} \vec{r}\)
- \(\kappa \frac{e^{2}}{r^{3}} \hat{r}\)
Answer
(C) - e^ 2 r^ 3 r
