Could someone please look at the problem below and see if i am on the right lines of solving it? I am finding the whole subject of circular motion hard to get my head around and therefore not 100% confident in my workings. I have also attached my free body diagram.
Calculate the tension in a 3m string attached to a 3kg bob that is moving in horizontal circles of 0.6m radius
Tanθ = Opposite/Hypotenuse
TCosθ = mg
θ = Tan1 0.6/3
θ = 10.32°
TCosθ = mg
T = mg/Cosθ
T = (3Kg x 9.81) / Cos 10.32
T = 29.91 N
