Question 219: Laws of Motion

Question

Two bodies of mass 4 kg and 6 kg are tied to the ends of a massless string. The string passes over a pulley which is frictionless (see figure). The acceleration of the system in terms of acceleration due to gravity (g) is :

Accepted Answer

Acceleration of the masses is given to be :
$$a = {{\left( {{m_1} - {m_2}} \right)g} \over {\left( {{m_1} + {m_{}}} \right)}}$$
where, $${m_1} > {m_2}$$
$$a = {{\left( {6 - 4} \right)g} \over {6 + 4}}$$
$$a = {g \over 5}$$
