Two blocks of 3 kg and 4 kg resting on a smooth horizontal surface are joined by a light inextensible string. The 4 kg block is pulled horizontally by a force of $18$ N. The common acceleration of the blocks is:
Options:
Answer:
C
Solution:
$a = \frac{18}{3 + 4} = \frac{18}{7} \approx 2.57 m/ s^{2} .$
