mass of stone=100gm=0.1kg
the downward force is mg
so the force needed to lift the stone must be greater than mg
F>mg
F>0.1×10
F>1N

F=ma
let the force applying downward be mg=f.
and the force required to lift be F.
m=100g = 0.1 kg
a=g=9.8m/sec^2
therefore,
f=mg
=0.1×9.8
=0.98 kg-m/sec^2
= 0.98 N
F > f
therefore, the force required to lift 100g stone should be anything but greater than 0.98 N
