    The apparent weight of a man in a lift is W_(1) when lift moves upwards with some acceleration and is W_(2) when it is accerating down with same acceleration. Find the true weight of the man and acceleration of lift .

    A man stands on a weighing machine kept inside a lift. Initially the lift is ascending with the acceleration 'a' due to which the reading is W . Now the lift decends with the same acceleration and reading 10% of initial. Find the acceleration of lift ?

    Assertion : In the case of free fall of the lift, the man will feel weightlessness. Reason : In free fall, acceleration of lift is equal to acceleration due to gravity.
