Connected Bodies & Pulleys

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:

Show answer and solution

Answer: (b)

$a = \dfrac{(m_2 - m_1)g}{m_1 + m_2} = \dfrac{(6 - 4)g}{10}$
$a = \dfrac{g}{5}$ , so the answer is (b).
