A weight can be hung in any of the following four ways by string of same type. In which case is the string most likely to break?

A

$C$

B

$B$

C

$A$

D

$D$

Solution

$2 T \cos \theta= mg$

$T=\frac{m g}{2 \cos \theta}$

$\theta \uparrow, \cos \theta \downarrow$ and $T \uparrow$

If tension is more than string may be break
