D
Text Solution
Verified by ExpertsThe correct answer is:
C
The net force acting on the stone in a downward direction would be equal to 
, where m is the mass of the stone. The force acting downwards would be equal to 
due to its weight and the force acting upwards would be equal to 
due to the buoyant force.
Hence, we get
