A man of mass m=60kg is standing on weighing machine fixed on a triangular wedge of angle `theta`=`60^(@)` as shown in the figure. The wedge is moving up with an upward acceleration `alpha=2m//s^(2)`. The weight regiatered by machine is

A

600 N

B

1440 N

C

360 N

D

240 N

Text Solution

Verified by Experts

The correct Answer is:
C
`N-mg cos theta=ma cos theta`
`N=m(g+a)cos theta=60(10+2)cos60^(@)`
`=360N`
