Why A Nail Of Iron Sinks In Water Whereas, A Large Ship Also Made Of Iron Floats?

Answer»

In case of a nail the BUOYANT (the upward) force is less than the downward force DUE to WEIGHT of the nail. In case of a SHIP, the buoyant force is GREATER than the weight of the ship. Buoyant force is the upward thrust of a fluid.
