Q. A block of $\sqrt{3}\, kg$ is attached to a string whose other end is attached to the wall. An unknown force $F$ is applied so that the string makes an angle of $30^{\circ}$ with the wall. The tension $T$ is: (Given $g =10 \,ms ^{-2}$ )Physics Question Image

Solution:

$ \theta=30^{\circ} $
$ \cos \theta=\frac{\sqrt{3} g}{ T } $
$ \Rightarrow \frac{\sqrt{3}}{2}=\frac{\sqrt{3} g}{ T } $
$ \Rightarrow T =20\,N $
