363316 A \(1\,kg\) mass is suspended from the ceiling by a rope of length \(4 m\). A horizontal force ' \(F\) ' is applied at the mid point of the rope so that the rope makes an angle of \(45^{\circ}\) with respect to the vertical axis as shown in figure. The magnitude of \(F\) is (Assume that the system is in equilibrium and \(g = 10\;m/{s^2}\) )
