A person is standing in an elevator. In which situation, he experiences weight loss ?

Options

  1. AWhen the elevator moves upward with constant acceleration
  2. BWhen the elevator moves downward with constant acceleration
  3. CWhen the elevator moves upward with uniform velocity
  4. DWhen the elevator moves downward with uniform velocity

Correct answer

B. When the elevator moves downward with constant acceleration

Step-by-step solution

When the pseudo force acting on the person is in opposite direction to the weight then the person will experience weight loss. The direction of the pseudo force is opposite to the direction of the frame of reference. Hence, B is the correct answer.
