Calculate $T_1$ and $T_2$

For given systen ${\theta _1}$ ……. $^o$ 

A body of weight $2\, kg$ is suspended as shown in the figure. The tension ${T_1}$ in the horizontal string (in kg wt) is

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 uniform sphere of weight $W$ and radius $3\,m$ is being held by a string of length $2\,m$ , attached to a frictionless wall as shown in the figure. The tension in the string will be
