Question 47

A particle P, of mass 10 kg, is held in equilibrium attached to two light inextensible strings. String A is at an angle of 30∘ 30^\circ\,30∘ to the horizontal. String B is at an angle of 60∘ 60^\circ\,60∘ to the horizontal as shown in the diagram.

A particle P is held by two strings attached to points A and B on a horizontal support, with the strings making angles of 30° and 60° to the horizontal.
