1.	Two masses (M+m) and (M-m) are attached to the ends of a light inextensible string and the string is made to pass over the surface of a smooth fixed pulley. When the masses are released from rest, the acceleration of the system is
Answer» `gm//M` `2gM//m` `gm//2M` `G(M^(2)-m^(2))//2M` SOLUTION :`a=g[(m_(2)-m_(1))/(m_(1)+m_(2))]`
