Problem: A 0.400-kg object is swung in a circular pathand in a vertical plane on a 0.500-m-length string. If theangular speed at the bottom is 8.oo rad/s, what is the tension inthe string when the object is at the bottom of the circle? Need help and pleased show calculations!

Explanation / Answer

so mg and centrifugal force acts on it that will be balanced bytension so T =mg+mw2r =0.4*(10+64*0.5) = 16.8N
