Consider the situation shown in figure. The system is released from rest and the block A travels a distance 5m in downward direction, then work done by tension on the block B :-

Options:

Answer:

Solution:

$s_{A} = 2 s_{B}, a_{A} = 2 a_{B} = 2 a$

$100 - T = 10 (2 a)$

$2 T - 50 = 5 a$

$T = \frac{100}{3} N$

$s_{A} = 5 m \Rightarrow s_{B} = 2.5 m$

$W_{B} = (2 T) s_{B}$

$W_{B} = \frac{200}{3} \times 2.5 = \frac{500}{3} J$

$W_{B} \approx 166.67 J (B)$
