Solution
When an elevator starts to rise suddenly, it accelerates upward. The floor must exert an extra upward force on the passenger to accelerate them with the elevator.
R − mg = ma
R = m(g + a)
Since R > mg, the apparent weight increases and the person feels heavier, not weightless.
Therefore, the statement is incorrect: weightlessness is experienced when an elevator falls freely downward, not when it suddenly starts rising.
