An object on a vertical spring is moving up and down. When the object is at its lowest point, which of the following statements is/are true :
Options:(select one or more)
Answer:
A, C, D
Solution:
At the lowest point the body momentarily stops before moving up, so its velocity is zero - (A) correct.
The lowest point is the extreme of the oscillation: the spring is stretched the most, so the upward spring force exceeds mg and the net force (and hence acceleration) is upward, not zero - (C) correct, (B) wrong.
Being the extreme position, the displacement from the equilibrium position is maximum - (D) correct.
Correct options: (A), (C), (D).
