the unit of weight is newton(kgf)
1 kgf is the force on 1 kg mass influenced by acceleration due to gravity
1kgf=9.8 N
now,the weight of the wooden block=200gf=0.2kgf=0.2×9.8 N=1.96 N
since the block is floating on water ,it's weight is balanced by upthrust due to water...
thus upthrust due to water=1.96N
hope it helps....
