A body falling freely under the action of gravity has

  • Q. A body falling freely under the action of gravity has
  • filter_dramaExplanation
    Answer is : A

    The correct answer is No weight.

    Explanation:

    • Gravity is a force that attracts a body toward the centre of the earth or any other mass-bearing physical body.

    F = mg
    where F is force, 
    m is mass, and 
    g is acceleration due to gravity.

    • The weight of an object is the force that attracts it to the earth.
    • A body that is free to fall under the influence of gravity is acted upon by the force of gravity.
    • However, the object is not exerting any force on any surface. As a result, the weight of object is no weight (zero).
