Q. Two masses of $5\ kg$ and $10\ kg$ are connected to a pulley as shown. What will be the acceleration of the system ($g =$ acceleration due to gravity)
A) $g$
B) $\frac{g}{2}$
C) $\frac{g}{3}$
D) $\frac{g}{4}$
Explanation
(c) $a = \frac{m_{2} - m_{1}}{m_{1} + m_{2}}g = \frac{10 - 5}{10 + 5}g = \frac{g}{3}$
