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

A

Zero

B

400 N

C

800 N

D

1200 N

Text Solution

Verified by Experts

The correct Answer is:
D
Reading of weighing scale = m(g+a)
=80(10+5)=1200 N
