Question

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

विकल्प

• t₁ = t₂

• t₁ < t₂

•  t₁ > t₂

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

Answer 1

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.
