Question

An electron revolves around the nucleus of hydrogen atom in a circular orbit of radius 5 x 10^-11 m.

Calculate:

(i) intensity of electric field of the nucleus at the position of the electron.

(ii) electrostatic potential energy of the hydrogen nucleus and electron system

Answer 1

(i) Here r = 5 x 10^-11m, + e = 1.6 x 10^-19C

Electric intensity at the position of the electron

(ii)  Electronstatic potential energy
