Hey guys, this is my first time posting and I really need your help.(adsbygoogle = window.adsbygoogle || []).push({});

I'm stuck on this question:

A light inextensible string of length 40cm has its upper end fixed at a point A, and carries a mass of 2kg at its lower end. A horizontal force applied to the mass keeps it in equilibrium, 20cm from the vertical through A. Find the magnitude of this horizontal force and the tension in the string.

From this I think I only know one force which would be 2g. I also know the lengths but what to do with them?!

I'm guessing I have to usetrigonometry? I'm really clueless and don't know where to start. I can't even think of what the diagram would look like. I'd appreciate any help!

I tried making a triangle, with sides 0.2,0.4 and 2g. Don't know how this will help tho :(

Thanks in advance
