Q3:
A spinning disk has a string that holds a small sphere that
has a mass of 16 g. The string is suspended from a point at a negligible distance
from its center, as shown in the diagram. The disk rotates uniformly around its
center with an angular velocity of 24 rad/s. The string makes an angle of
with the axis of rotation of the disk.
What is the magnitude of the vertical force exerted on the
sphere by the string?
What is the distance between the diskโs axis of
rotation and the circular path followed by the sphere?
What is the magnitude of the horizontal force exerted on the
sphere by the string?
What is the magnitude of the net force exerted on the sphere
by the string?
