Q160 · Physics

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 :

The figure, described in words

Atwood machine: fixed frictionless pulley with 4 kg block hanging on the left and 6 kg block hanging lower on the right.
