Question 591: Atoms & Nuclei

Question

An electron is moving round the nucleus of a hydrogen atom in a circular orbit of radius r. The Coulomb force $$\overrightarrow F $$ between the two is

Accepted Answer

The charge on hydrogen nucleus q
1
= +e
charge on electron, q
2
= Ã¢ÂÂe
Coulomb force, F = $$K{{\left( { + e} \right)\left( { - e} \right)} \over {{r^2}}}$$
= $$ - {{K{e^2}} \over {{r^3}}}\overrightarrow r $$
= $$ - {{K{e^2}} \over {{r^2}}}\widehat r$$

Answer

$$K{{{e^2}} \over {{r^2}}}\widehat r$$

Answer

$$ - K{{{e^2}} \over {{r^3}}}\widehat r$$

Answer

$$K{{{e^2}} \over {{r^3}}}\widehat r$$

Answer

$$ - K{{{e^2}} \over {{r^2}}}\widehat r$$
