Question 36

A particle P is attached to a wall by a light inextensible string. A horizontal force of k k\,k N is applied to P. The particle is in equilibrium with the string taut making a 25∘ 25^\circ\,25∘ angle with the vertical as shown in the diagram.

A particle P is attached to a vertical wall by a taut string at 25° to the vertical, with a horizontal force of k N acting to the right.

a.

Find, in terms of kkk, the tension in the string

[2]
b.

Find, in terms of kkk, the weight of P
