Question

After terminal velocity to reached, the acceleration of a body falling through a fluid is

  1. equal to g
  2. zero
  3. less than g
  4. more than g

Answer

zero

Explanation

When an object is dropped in a fluid, it experiences a drag force that opposes its motion. Initially, the object accelerates due to the gravitational force, but as the speed of the object increases, the drag force also increases until it becomes equal and opposite to the gravitational force. At this point, the net force acting on the object becomes zero, and it stops accelerating.
