A 2.5 x 10-g mass is attached to the end of a 1.2 m long string and twirled in a circle that forms a vertical plane. (a) What is the minimum Period required to keep the mass moving in this circle? (b) What is the minimum Tension in the string at the minimum period? (c) At what location on the circle's path does the maximum Tension occur (c) Calculate the maximum Tension in the string at this location when being twirled at the minimum period
