Solution

The correct option is C v/3
$^{'} B^{'} e x p e r i e n c e s^{'} 3 T^{'} T e n s i o n f o r c e$
and A experiences 'T' Tension force.
$S o 3 T \times V B = T X V A$
$V_{B} = \frac{V_{A}}{3}$
So Answer is (C).

The correct option is C v/3′B′experiences′3T′Tensionforce and A experiences 'T' Tension force. So3T×VB=TXVAVB=VA3So Answer is (C).

The correct option is C v/3
$^{'} B^{'} e x p e r i e n c e s^{'} 3 T^{'} T e n s i o n f o r c e$
and A experiences 'T' Tension force.
$S o 3 T \times V B = T X V A$
$V_{B} = \frac{V_{A}}{3}$
So Answer is (C).
