Question

A body weighs more in air and less in water give reason why?​

Answer 1

Answer:

The apparent weight of body is less in air than in vacuum. This follows from Archimedes principle , which explains the loss in weight of a body immersed in a fluid, due to the upthrust . But in vacuum, there is no upthrust and hence no loss in wieght of a body. That is why a body weighs more in vacuum than in air .
