Question

A 100 kg man stands on bathroom scale inside an elevator, on planet where free fall acceleration is 10 m.s^2. Elevator which was initially at rest starts moving moving up with constant acceleration 5 m/s^2. Reading of the scale is

Answer 1

Answer:

The scale will read 1kN

Explanation:

The man will feel heavy than they really are (because the floor is pushing up on them with a force larger than their weight)

like wise if the elevator descends the man will feel lighter than he is

we know

Force= mass X acceleration due to gravity

given that the mass m of the man=100kg

free fall acceleration is= 10 m.s^2.

the scale reading will be equal to the force F

F=100*10

F=1000N

The scale will read 1000N or 1kN
