Explanation:
Normal weight of the gold bar = 5.0 × 9.81 = 49.05 N
The weight of the gold bar would be reduced because of the buoyant force acting upwards.
weight of the gold bar under water = normal weight - weight of the water displaced by the gold bar.
first, we need to find the volume (V) of the gold bar.
Percentage of decrease in weight
