Q. $T_{1}$ and $T_{2}$ in the given figure are

28 N , 48 N

48 N , 28 N

96 N , 56 N

56 N , 96 N

Acceleration of the system
$a = \frac{F _{ext}}{M _{Total}} = \frac{120}{3 + 5 + 7} = 8 m / s^{2}$
Writing equation for $7 k g$ mass
$T_{2} = 7 (8)$
$= 56 N$
Writing equation for $5 k g$ mass
$T_{1} = T_{2} + 5 (a)$
$= 56 + 5 (8) = 96 N$

Q. T1​ and T2​ in the given figure are
