An elevator is accelerating upwards with an acceleration of `6m//s^(2)` . Inside it a person of mass 50kg is standing on a weighing machine which is kept on an inclined plane having angle of inclination `60^(@)` . The reading of the weighing machine is:

A

40kg

B

160kg

C

80kg

D

50kg

Text Solution

Verified by Experts

The correct Answer is:
A
`N-mgcos60^(@)=macos60^(@)`
`N=mcos60^(@)(a+g)=400N`
Reading will be `40kg`
