1. Use the archimedes principle ,
mass of body ,m=1kg ,
weight of body W=mg=9.8N
Buoyant force, Fb= weight of water displaced by the body
Mass of the water displaced, Mw= 100*10^-6 * 1000 = 0.1kg
Weight of water , Wb = 0.1*9.8= 0.98N = Fb
Weight of the body in water, Ww= 9.8-0.98= 8.82N(Ans)
In the unit of kgf, Ww= 8.82/9.8 = 0.9kgf
