Q7. Will a body weigh more in air or in vacuum when weighed with a spring balance? Explain your answer.
Hi Ayuash!
Weight of a body is the force experienced by the body due to gravity. If the body is in air, the buoyant force of the air reduces its weight. A body weighed in vacuum will show a slight increase in the weight of the body. However, this increase in weight is negligible.
