Question 9 Not yet answered Marked out of 7.00 p Flag question A small sphere of mass m and radius 7 starts from rest at height h, and rolls without slipping along the track shown in the figure. The radius of the loop (R) is much larger than the radius of the sphere). ith = 3R find the magnitude of the normal force acting on the sphere at point p which is at the horizontal end of the circular track. (The moment of inertia of the sphere is I = m) Figure P10.79 Sweet Select one 3. N= 10 mg mo n. N N - me
