    Have you tried anything so far? Resolve vertically upwards and it should be fairly straightforward.

    (If you're unsure, remember that forces have both a horizontal and vertical component)

    I did not think of using horizontal and vertical forces, I will try it thanks, None of the other questions asked for horizontal or vertical forces and I really hate these string questions they confused me :P but thanks I'll try it

    I've tried it but I still have no clue what I'm doing, I don't know how to answer this question all I did was

    1.5sin(50) = 1.15

    I literally don't know what I'm doing and its also because there are 2 strings, I don't know how to answer this question hellp ? Thanks again

    Hmm, where did you get the 1.5 from in front of the sin50?

    Let me put in the components of the force of the string to see if that helps:

    Try resolving vertically upwards
