A tetherball leans against the smooth, frictionless post to which it is attached. The string is attached to the center of the ball. If the string is l=1.20 m long and the ball has a radius r=0.150 m with mass m=0.250 kg, what is the magnitude T of the tension in the rope and what is the magnitude Fₚ​ of the force the pole exerts on the ball?
