Question

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 which of the following option is correct?

Professor PC Thomas Classes · Answer

If elevator moves uniformly, acceleration is zero. Effective gravity remains $g$. Thus $t_1 = t_2$.
