Water and air are both fluids. why is it easier to lift a rock in water rather than lifting a rock in air? the buoyant force is greater on the rock in air. the force of gravity on the rock is greater in water. the buoyant force is greater on the rock in water. the force of gravity on the rock is less in water.                                                                                              is it me or is this question not like the hits blunt meme

the correct choice is

The buoyant force is greater on the rock in water

Explanation :

The buoyant force acting on a rock completely submerged  in a fluid is given as

F = ρ V g            

here   F = force of buoyancy

V = Volume of fluid displaced by the rock (in case of object completely inside the fluid, the volume of fluid displaced is same as the volume of object)

g = acceleration due to gravity.

from the formula , the force of buoyancy "F" in upward direction is directly proportional to the density of fluid displaced. that is , greater the density of fluid , greater will be the force of buoyancy.

we know that density of water > density of air.

hence the rock experience greater force of buoyancy inside water as compared to when in air.

greater force of buoyancy inside water makes it easier to lift the rock in water.
