1. The problem statement, all variables and given/known data A particle of mass 15g is attached to the end of a string of length 50cm, rotating at 6rads-1 to form a conical pendulum. Find a) The tension in the string Find b) The angle 2. The attempt at a solution Okay I get that Tcosθ= mg & TSinθ= mv^2/r which => tanθ= v^2/rg and I get why, but I don't understand how to find tension..... I'm really blooming confused and have been banging my head for over two hours now. I also know I need to find r using the length of the string and the angular velocity, I just don't get how. Basically, I need r to find both and I can't work out how to get r? Please, someone help me?? Thanks!
