Question

Charge q of mass m revolves around a point charge q due to electrostatic attraction period if revolutuon

Answer 1

you mean, we have to find time period of charged particle , right ?

a charge particle q of mass m is revolving around a point charge Q due to electrostatic force of attraction.

so, electrostatic force acting between them is balanced by centripetal force

$\frac{kq^2}{r^2}=m\omega^2r$

or, $\omega^2=\frac{kq^2}{mr^3}$

or, $\omega=\sqrt{\frac{kq^2}{mr^3}}$

we know, angular velocity= 2π/Time period

so,$T=2\pi\sqrt{\frac{mr^3}{kq^2}}$

hence, time period is $T=2\pi\sqrt{\frac{mr^3}{kq^2}}$
