weight of water displaced by the object in liquid A = 10 - 8 = 2 N
weight of liquid displaced in liquid B = 10 - 9 = 1 N
we know weight of water displaced = volume of the object and ,
volume of the water displaced = upthrust force
2 N>1 N
when the object was in liquid A it has experienced more upthrust force
i hope it helps.........
