MCQ
A weight can be hung in any of following four ways by using same string. In which case is the string more likely to break is :-
- A$A$
- B$B$
- ✓$C$
- D$D$
✓
Answer
Correct option: C.
$C$
c
$2 \mathrm{T} \cos \theta=\mathrm{mg} ; \mathrm{T}=\frac{\mathrm{mg}}{2 \cos \theta}$
$2 \mathrm{T} \cos \theta=\mathrm{mg} ; \mathrm{T}=\frac{\mathrm{mg}}{2 \cos \theta}$
$\cos \theta$ less or $\theta$ more tension more
