A man weighs 80 ~kg . He stands on a weighing scale in a lift which is moving upwards with a uniform acceleration of 5 ~m / s ^2 . What would be the reading on the scale? (g=10 ~m / s ^2 )

Options

  1. Azero
  2. B400 ~N
  3. C800 ~N
  4. D1200 ~N

Correct answer

D. 1200 ~N

Step-by-step solution

Reading of weighing scale aligned & =m(g+a) & =80(10+5)=1200 ~N aligned
