Text Solution
Verified by ExpertsThe correct answer is:
D
The moment coin falls into the water, the weight of the block decreases, as a result the block rises up and therefore l decreases.
Further, with the rise of the block, the volume of displaced water also decreases, as a result the water level in the tank falls and thus h also decreases.
