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