MCQ

A person standing on the floor of an elevator drops a coin. The coin reaches the floor of the elevator in time t1 if the elevator is stationary and in time t2 if it is moving uniformly. Then

Options

  • t1 = t2

  • t1 < t2

  •  t1 > t2

  • t1 < t2 or t1 > t2 depending on whether the lift is going up or down.

Solution

t1 = t2
After the coin is dropped, the only force acting on it is gravity, which is same for both the cases.
So t1 = t2.
