1. A 560 g hollow ball 18 cm in diameter is suspended by a wire and is undergoing torsional oscillations at a frequency of 0.78 Hz. What is the torsional constant of the wire?
F=-κθ
ω=sqrt(κ/I)
tried to use the frequency to get the angular displacement and then just solve for k but I didn't get the answer
