the force of gravity does not change in water, it is equal to mass*g.
What changes in water is the upward bouyancy force, which against the force of gravity.
But the force of gravity is still pulling it downward. If it is floating, the NET force is zero. If it sinks, the net force is weight-bouyancy.
Wording of this problem could have been improved.
A steel block has a volume of 0.08 m and a density of 7,840 kg/m. What is the force of gravity acting on the block ( the weight ) in water?
