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 :

Options:

\(\frac{g}{5}\)

\(\frac{g}{10}\)

g

\(\frac{g}{2}\)

Correct Answer:

\(\frac{g}{5}\)

Explanation:

a = \(\frac{m_1 - m_2}{m_1 + m_2}g\) ; m1 > m2

m1 = 6 ; m2 = 4

a = \(\frac{g}{5}\).
