Ans is option d
In case of accelerating downward the net force on the lift by man decreases as the net value of acceleration is smaller than g due to an applied pseudo acceleration......
see the attachement....
agr acceleration km hai to force bhi to km hi hoga naa
because Force = Mass*Acceleration
man ka weight hai Mg
pr is case mein jo force aayega vo hoga
M(g-a)
to clear hai ki force applied force by man on the lift is less than the weight of the man
