Detailed Solution

The above statement is false.
According to Archimedes principle,
apparent weight of cork= weight of the cork-the weight of displaced liquid.
When the cork is floating in the liquid, the weight of the cork is equal to the weight of the volume of the liquid displaced. So, the apparent weight = 0. we can say that only the apparent weight will be zero.
The correct statement would be that a cork floating in water is not weightless.
