Two blocks of masses m and M are connected by means of a metal wire of cross-sectional area A passing over a frictionless fixed pulley as shown in the figure. The system is then released. If $\displaystyle \mathrm{M}=2 \mathrm{~m}$, then the stress produced in the wire is :
Official answer
(2)
$\displaystyle \frac{4 \mathrm{mg}}{3 \mathrm{~A}}$
