A block $A$ of mass $7\ kg$ is placed on a frictionless table. A thread tied to it passes over a frictionless pulley and carries a body $B$ of mass $3\ kg$ at the other end. The acceleration of the system is (given $g = 10\ ms^{- 2}$)

(b) $a = \frac{m_{2}}{m_{1} + m_{2}}g = \frac{3}{7 + 3}10 = 3\ m/s^{2}$
