Forces and equilibrium — practice question
A block with mass $15\,\text{kg}$ is suspended in equilibrium from a horizontal ceiling by two strings, as the diagram shows. One string makes an angle of $45^\circ$ with the horizontal and has tension $120\,\text{N}$. The second string is at $\theta^\circ$ to the horizontal and carries tension $T\,\text{N}$.
