Problem $2$

A lamp with mass $m=18kg$ is suspended $70$ cm from the ceiling using two massless, unstretchable cables as shown in the figure. The length of cable $1($left cable$)$ is $80$ cm while the length of cable $2($right cable$)$ is $140$ cm $.$

A$.$ Draw the Free Body Diagram for the lamp

B$.$ What are the angles $$ and $?$

C$.$ What are the magnitudes of the tensions in the two cables: $T_{\text{l}\text{e}\text{f}\text{t}}$
