Three blocks of masses \( m_{1}, m_{2} \) and \( m_{3} \) are connected by massless string as shown kept on a frictionless
P table.
\( \mathrm{W} \)
They are pulled with a force \( T_{3}=40 \mathrm{~N} \). If \( m_{1}=10 \mathrm{~kg} \), \( m_{2}=6 \mathrm{~kg} \) and \( m_{3}=4 \mathrm{~kg} \), the tension \( T_{2} \) will be
(1) \( 20 \mathrm{~N} \)
(2) \( 40 \mathrm{~N} \)
(3) \( 10 \mathrm{~N} \)
(4) \( 32 \mathrm{~N} \)
