Question

A particle of charge ${ }^{\prime}-q$ ' and mass ${ }^{\prime} m$ ' moves in a circle of radius ${ }^{\prime} r$ ' around an infinitely long line charge of linear density ' $+\lambda$ '. Then time period will be given as: (Consider k as Coulomb's constant)

Select the correct option:

$\mathrm{T}^2=\frac{4 \pi^2 \mathrm{~m}}{2 \mathrm{k} \lambda \mathrm{q}} \mathrm{r}^3$

$\mathrm{T}=2 \pi \mathrm{r} \sqrt{\frac{\mathrm{m}}{2 \mathrm{k} \lambda \mathrm{q}}}$

$ \mathrm{T}=\frac{1}{2 \pi \mathrm{r}} \sqrt{\frac{\mathrm{~m}}{2 \mathrm{k} \lambda \mathrm{q}}} $

$\mathrm{T}=\frac{1}{2 \pi} \sqrt{\frac{2 \mathrm{k} \lambda \mathrm{q}}{\mathrm{m}}}$

✓ Correct! Well done.
