A body of mass m is attached to a spring balance which is attached to the ceiling of an elevator. If the elevator moves up with a certain acceleration, the apparent weight of the body will be
Correct answer: D. All of these
- A. m(g+a)
- B. g(m+ma/g )
- C. a(m+mg/a )
- D. All of these
Explanation
The apparent weight of the body in an elevator depends on the acceleration of the elevator and the gravitational acceleration.Upward acceleration: The apparent weight is m(g + a).Downward acceleration: The apparent weight is m(g - a).
