Question 2

Equilibrium of Forces

A body When slightly displaced is said to be in neutral equilibrium only if it tends to

  1. A.come to rest in a new position with centre of - gravity and height remaining unchanged
  2. B.return to its original position
  3. C.remain in its displaced position
  4. D.move further away from its original position while its centre of mass changes.
Show the answer and explanation

Answer: A (come to rest in a new position with centre of - gravity and height remaining unchanged)

Explanation

In neutral equilibrium (like a ball on a flat floor) a displaced body settles in its new position and its centre of gravity stays at the same height.
