A particle of charge $-q$ and mass $m$ moves in a circle of radius $r$ around an infinitely long line of charge having linear charge density $+\lambda$ . The time period $T$ is given by:

A
$T^2 = \frac{4\pi^2 m r^3}{2k q \lambda}$
B
$T = 2\pi r \sqrt{\frac{m}{2k q \lambda}}$
C
$T = \frac{1}{2\pi r}\sqrt{\frac{m}{2k q \lambda}}$
D
$T = \frac{1}{2\pi}\sqrt{\frac{2k q \lambda}{m}}$
