If a spring balance is used to weigh a body, will the weight of the body be the same in vacuum and air? Explain why. |
Answer» When a body is suspended in air, the buoyant force acts on the body. Hence, the magnitude of the net downward force on 1 the body = the magnitude of the weight of the body – the magnitude of the buoyant force on the body. Hence, when a spring balance is used to weigh a body, the weight of the body in air is less than that in vacuum. |
