13. The free-body force diagram shows the three forces acting on a heavy pendulum that has been pulled sideways by a horizontal force. The string makes an angle of \( 20^{\circ} \) with the vertical. The tension in it is \( 35 \mathrm{~N} \). Use the vertical and horizontal components of the tension to find the welght, \( W \), of the pendulum and the horizontal force, \( \mathrm{F} \), used to pull it to one side. [32.9N, 12.0N]
