Motion of a ball bearing inside a smooth fixed bowl, when released from a point slightly above the lower point is
(A) simple harmonic motion.
(B) non-periodic motion.
(C) periodic motion.
(D) non-oscillatory motion
Options
- AA, C
- BB, D
- CC, D
- DNone
Correct answer
A. A, C
Step-by-step solution
- Simple Harmonic Motion (SHM):
When the ball bearing is released from a point slightly above the lowest point in a smooth fixed bowl, it will oscillate about the lowest point. The motion is characterized by a restoring force that is proportional to the displacement from the equilibrium position (the lowest point). Therefore, this motion can be considered simple harmonic motion.
- Periodic Motion: The motion of the ball bearing is also periodic because it repeats itself in a regular interval as it moves back and forth.
Conclusion:
Since the motion fits both categories of simple harmonic motion and periodic motion, the correct choice is (1) A, C.
