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 :
Answer: (C) g/5
For an Atwood machine:
$$a = \frac{(m_2 - m_1)g}{m_1 + m_2} = \frac{(6 - 4)g}{10} = \frac{g}{5}$$
