Question

Three boxes are placed in a lift.When acceleration of the lift is 4 m/s^2 ,the net force on the 8 kg box is equal to

Answer 1

As we know

Force = mass × acceleration

Force = 24 × 4 ( there are three boxes , each weighing 8 kg)

Force =96 Newton

Answer 2

Answer:

32 N

Explanation:

As lift is moving with a=4 then box also move with a=4 so net force on 8kg is

F=ma

8×4=32N
