Q 11-04-112JEE MainJEE Main 2023 (24 Jan, Shift 1)Easy
Given below are two statements:
**Statement I:** An elevator can go up or down with uniform speed when its weight is balanced with the tension of its cable.
**Statement II:** Force exerted by the floor of an elevator on the foot of a person standing on it is more than his/her weight when the elevator goes down with increasing speed.
In the light of the above statements, choose the correct answer from the options given below:
Answer: (B) Statement I is true but Statement II is false
Uniform speed means zero acceleration, so the tension balances the weight: Statement I is true.
Going down with increasing speed means acceleration $a$ downward: $N=m(g-a)<mg$. Statement II is false.
