A particle P P\,P is attached to a vertical wall by a light inextensible string. A horizontal force of magnitude 20 N is applied to PPP.
The particle rests in equilibrium with the string taut and making an angle of 25° 25°\,25° with the vertical, as shown in the diagram.
Find the tension in the string.
Find the weight of PPP.
