A mass of $\displaystyle 10$ kg is suspended vertically by a rope from the roof. When a horizontal force is applied on the rope at some point, the rope deviated at an angle of $\displaystyle 45^{\circ}$ at the roof point. If the suspended mass is at equilibrium, the magnitude of the force applied is $\displaystyle \left(\mathrm{g}=10 \mathrm{~ms}^{-2}\right)$
Official answer
(1)
$\displaystyle 100$ N
