A person stands on a weighing machine kept on the floor of an elevator .When the elevator is at rest then the apparent weight of the person is

(A) : The apparent weight of a body in an elevator moving with some downward acceleration is always less than the actual weight of body. (R) : Normal reaction force by the floor of elevator on the body is less than the weight of the body when elevator is moving down

If the tension in the cable supporting an elevator is equal to the weight of the elevator, the elevator may be :

A person standing on the floor of an elevator drops a coin. The coin reaches the floor in time t_1 if the elevator is at rest and in time t_2 if the elevator is moving uniformly. Then
