Vedclass · Answer

Block $A: 2 T=5(a / 2) \Rightarrow a=\frac{4 T}{5}$           $...(1)$

Block $B: 2 g-T=2(a)$                     $...(2)$

$\Rightarrow 2 g-T=2 	imes \frac{4 T}{5}$

$\Rightarrow \frac{13}{5} \mathrm{T}=2 \mathrm{g}$

$\mathrm{T}=\frac{10}{13} \mathrm{gN}=\frac{10}{13} \mathrm{kg}$

Reading $=\mathrm{T}=\frac{10}{13} \mathrm{kg}$
