Question

Determine the force of electrostatic interaction between the nucleus & the electron in hydrogen atom.
The mean distance between of the electron from the nucleus of the atom is \[1 \times 10^{-8}cm.\]and the charge of the electron is "e" \[e=4.8 \times 10^{-10}\space \space \text{cgs electrostatic units. }\]Answer must be in Dynes.
