An electron is moving around the nucleus of a hydrogen atom in a circular orbit of radius $r$ . The coulomb force $F$ between the two is: $($ where $K = \frac{1}{4 π ε _{0}})$ NEET 2003

Options:

Answer:

Solution:

The charge on hydrogen nuclear $q_{1}$ $= + v e ∴ Coulomb’s force F = K \frac{q _{1} q _{2}}{r ^{2}} = K \frac{( + e ) ( - e )}{r ^{2}} = - \frac{k e ^{2}}{r ^{2}} \overset{r}{^}$
