Solution

The correct option is C
zero

We know that for block $m_{1}$ ,
$T = m_{1} g sin θ$ , where $θ = 30^{\circ}$

Acceleration is given as:
$a = \frac{Net pulling force}{Total mass}$

$a = \frac{m_{2} g - m_{1} g s i n θ}{m_{1} + m_{2}} = \frac{(4 g - 8 g s i n 30^{\circ})}{m_{1} + m_{2}} = 0$
