Question

If a body tied to a spring balance is fully immersed in a liquid, the apparent loss in its weight :
(1) is more in a denser liquid
(2) is less in a denser liquid
(3) does not depend on density of liquid
(4) is equal to apparent gain in weight of liquid

Answer 1

When a body is immersed in a liquid it feels an upward force, which is known as buoyant force. The buoyant force depends upon the weight of the liquid displaced by the body. Due to the presence of this upward buoyant force, the body undergoes in an apparent weight loss. More the density of the liquid more will be the weight of the liquid displaced by the body, so more apparent weight loss.

Hence, the correct answer is option 1.
