A particle ofmass 7 kg hangs from a point O by a light string. It is pulled aside by a force PN that makes an angle of 95 degrees with downward verticle and rest in equilibrum with the string inclined at an angle of 53 degrees to the verticle. Find P.

Could u also include the diagram, cheers!

i think it's one of those ones where it's like two strings attached to one mass.
eg.

Hope that's right =\ I'm not too good with purely worded dynamics questions, they get a bit confusing sometimes.
