MCQ
Acceleration of system is :-
- ✓$\frac{5g}{12}$
- B$\frac{3g}{12}$
- C$\frac{5g}{6}$
- DNone of these
✓
Answer
Correct option: A.
$\frac{5g}{12}$
a
$5 \mathrm{mg} \sin 30-\mathrm{T}=5 \mathrm{m} \times \mathrm{a}$
$5 \mathrm{mg} \sin 30-\mathrm{T}=5 \mathrm{m} \times \mathrm{a}$
$\mathrm{T}=\mathrm{m} \times \mathrm{a}$
$\frac{5 \mathrm{mg}}{2}=6 \mathrm{ma}$
$a=\frac{5 g}{12}$
