In Fig. 11-35, a solid brass ball of mass m will roll smoothlyalong a loop-the-loop track when released from rest along thestraight section. The circular loop has radius R, and the ball hasradius r << R. (a) What is h if the ball is on the verge ofleaving the track when it reaches the top of the loop? (b) If theball is released at height h = 6R, what is the magnitude of thehorizontal force component acting on the ball at point Q? Stateyour answers in terms of the given variables, using g whereapplicable.
