Question

Which demonstrates simple harmonic motion? a player dribbling a basketball a chandelier swinging from the ceiling a lion pacing the length of a cage a spring compressed in a ballpoint pen

Answer 1

The answer is B, since simple harmonic motion means restores the objects equilibruim, the chandelier is the only object that is swinging and restored back to it's equilibruim.

Answer 2

Answer : The correct option is (b).

Explanation :

The type of motion in which the restoring force is directly proportional to the displacement of a particle form the equilibrium position. This force acts in opposite direction.

`F\propto -x`

x is the displacement

The example that shows the simple harmonic motion is (b) " a chandelier swinging from the ceiling ". This is because a chandelier moves to and fro from its equilibrium position and restores it.
