Q. A mass of $ 6 \,kg $ is suspended by a rope of length $ 2\, m $ from a ceiling. A force of $ 50 \,N $ in the horizontal direction is applied at the mid-point of the rope. The angle made by the rope with the vertical, in equilibrium is
Solution:
$ \tan \theta =\frac{50}{6g}=0.83 $
or $ tan\text{ }\theta =tan\text{ }40{}^\circ $ or $ \theta =40{}^\circ $
