    the following cases in the elevator?
    A during free fall of a body under gravity Correct Answer Incorrect Answer
    B when elevator is accelerating downwards Correct Answer Incorrect Answer
    C when elevator is at rest Correct Answer Incorrect Answer
    D when elevator is accelerating upwards Correct Answer Incorrect Answer

    Solution

    The apparent weight of the body becomes zero in an elevator during free fall of a body under gravity. It can be said that the body becomes weightless as the force of reaction between the person and the plane with which he is in contact vanishes.
