Solution

The correct option is A $600 N$
Given that,

Mass of man $m = 60 k g$

Acceleration $= a m / s^{2}$

Velocity $= v m / s$

Now, weight of man on weighting machine going upward

$= m g + m a$

$= m (g + a)$

$= 60 (10 + 0)$

$= 600 N$

Hence, the the weight of man in weighting machine is $600 N$
