Spherical Velodrome
Two motorcycles are in circular movements on their respective tracks inside a spherical velodrome at their respective constant speeds, as shown above. The motorcycles A and B with the same mass have the same angular speed, and the two tracks are parallel to the ground. The radius of the track for A is smaller than that of the track for B. Which of the following statements is correct?
a) The period of the circular movement of A is smaller than that of B.
b) The speed of A is greater than that of B.
c) The net force acting on A is smaller than the net force acting on B.
