A person standing on the floor of an elevator drops a coin. The coin reaches the floor in time t1 if the elevator is at rest and in time t2 if the elevator is moving uniformly. Then
- t1 = t2
- t1 < t2 or t1 > t2 depending upon whether the lift is going up or down
- t1 < t2
- t1 > t2
Answer
(A) t 1 = t 2
