Solution

The correct option is A $25 N$
Let $T_{0} =$ tension in the string passing over A
and $T =$ tension in the string passing over B
$∴ 2 T_{0} = F$ and $2 T = T_{0}$
$\Rightarrow T = F / 4 = 100 / 4 = 25 N$

Find the tension in the string connecting the blocks if F is 100 N.

The correct option is A 25NLet T0= tension in the string passing over Aand T= tension in the string passing over B∴2T0=F and 2T=T0⇒T=F/4=100/4=25N

The correct option is A $25 N$
Let $T_{0} =$ tension in the string passing over A
and $T =$ tension in the string passing over B
$∴ 2 T_{0} = F$ and $2 T = T_{0}$
$\Rightarrow T = F / 4 = 100 / 4 = 25 N$
