Q8JEE Main 2023 · 24 JAN · SHIFT 1Easy

Apparent Weight & Lift

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:

Show answer and solution

Answer: (d)

  1. Statement I: uniform speed means a=0a = 0, so T=WT = W. True.
  2. Statement II: going down with increasing speed means aa is downward, so N=m(g−a)<mgN = m(g - a) < mg. False.
  3. So the answer is (d) Statement I is true but Statement II is false.
