A simple pendulum is made of a metal wire of length $L$, area of cross-section $A$, material of Young's modulus $Y$ and a bob of mass $m$. This pendulum is hung in abus moving with a uniform speed $v$ on a horizontal circular road of radius $R$. The elongation in the wire is

$\frac{m L}{R A Y} \sqrt{g^{2} R^{2}+v^{4}}$

$\frac{m g L}{A Y}$

$\frac{m L v^{2}}{R A Y}$

$\frac{L}{A Y} \sqrt{m g+\frac{m v^{2}}{R}}$
