20.Plot a graph of centripetal force vs. frequency. The graph should pass through the origin. Using the origin and the above data we can determine four values of f for a constant Fc of 12 units. Plot four lines of Fc vs. f2 on the same graph as shown below, one for each radius. (5) R = 1.25 m R = 0.75 m OR = 1.00 m R = 0.50 m 12 0 f2
