MCQ
$T_1$ and $T_2$ in the given figure are
- A$28\; N , 48\; N$
- B$48\; N , 28\; N$
- ✓$96 \;N , 56\; N$
- D$56 \;N , 96\; N$
✓
Answer
Correct option: C.
$96 \;N , 56\; N$
c
(c)
(c)
Acceleration of the system $a=\frac{F_{\text {ext }}}{M_{\text {Total }}}=\frac{120}{3+5+7}=8 \,m / s ^2$ Writing equation for $7 \,kg$ mass
$T_2=7(8)$
$=56 \,N$
Writing equation for $5 \,kg$ mass
$T_1=T_2+5(a)$
$=56+5(8)=96 \,N$
