हिन्दीTwo 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:
Correct answer · Option 2
g/5
Explanation
Acceleration \( a = \frac{m_2 - m_1}{m_2 + m_1} g = \frac{6 - 4}{6 + 4} g = \frac{2}{10} g = \frac{g}{5} \).
