A particle of charge ' $\displaystyle -q$ ' and mass ' $\displaystyle m$ ' moves in a circle of radius ' $\displaystyle r$ ' around an infinitely long line charge of linear charge density ' $\displaystyle +\lambda$ '. Then time period will be given as :
(Consider $\displaystyle k$ as Coulomb's constant)
Official answer
From NTA’s final answer key for this paper.
(1)
$\displaystyle T=2 \pi r \sqrt{\frac{m}{2 k \lambda q}}$
