An apple is held completely submerged just below the surface of water in a container. The apple is then moved to a deeper point in the water. Compared with the force needed to hold the apple just below the surface, what is the force needed to hold it at the deeper point?
a- smaller
b- larger
c- the same
d- impossible to determine

There will be apparent reduction in the weight of the apple due to buoyant force acting on it in upward direction . The magnitude of upward directing buoyant force will be equal to weight of water displaced . The weight of displaced water will remain same if it is completely submerged in water and it is moved from one point to another inside water. So in the given two cases , weight of displaced water will same . Hence the buoyant force too will remain same . Hence the apparent weight too will be same .

So force required to hold apple at deeper point inside water will remain same.

Scientific principles that relate to pressure can be helpful in answering questions such as this. So, compared with the force needed to hold the apple just below the surface, the force needed to hold it at the deeper point will be;

c- The same

Archimedes' principle is applied when solving this question. This principle states that 'when a body is fully or partially immersed in a fluid, the upward buoyant force acts on it is equal to the displaced fluid.'

Given this knowledge, we know that no matter the depth of the body in the fluid, the upward buoyant force will always be equal to the displaced fluid.

Therefore, the force needed to hold the apple at a deeper point will remain the same.
