Two bodies of mass m and M are hung at the ends of a rope passing over a frictional pulley. The acceleration in which the heavier mass M comes down is given by the following:
1
\(\frac{{g\left( {M - m} \right)}}{{M + m}}\)
2
\(\frac{{g\left( {M + m} \right)}}{{M-m}}\)
3
\(\frac{{gM}}{{M + m}}\)
4
\(\frac{{g \times M}}{{M - m}}\)
