Solution

Upthrust is the upward force acting on a body when it is partially or fully immersed in a liquid, it is also referred to as buoyant force.
[1 mark]
Upthrust acting on egg in fresh water is less than the weight of egg. Therefore, it sinks in fresh water. However, the density of salty water is much greater than the density of fresh water, so upthrust acting on egg in salty water is greater than the weight of egg. Therefore, it floats in salty water.
