Question 65

A particle P, of mass m m\,m kg, is held in equilibrium attached to two light inextensible strings. String A is at an angle of 50∘ 50^\circ\,50∘ to the horizontal. String B is at an angle of 35∘ 35^\circ\,35∘ to the horizontal as shown in the diagram.

The tensions in strings A and B are 80.6 N and 63.2 N respectively.

Diagram showing particle P held in equilibrium by two strings A and B, with A at 50° and B at 35° to the horizontal.

a.
