A person is standing in an elevator. In which situation he finds his weight less?A person is standing in an elevator. In which situation he finds his weight less?

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 elevator moves downward with constant acceleration, a=ga=g. Then person standing in an elevator find himself weightless. ( g′g^{\prime} with respect to the lift is (g−a))(g-a)) A person is standing in an elevator. In which situation he finds his weight less?
g′g^{\prime} with respect to the lift is . ggag g a is .
