A wooden block, with a coin placed on its top, floats in water as shown in figure. The distance `l` and `h` are shown there. After some time the coin falls into the water. Then

A

l decreases and h increases

B

l increases and h decreases

C

both l and h increase

D

both l and h decrease

Text Solution

Verified by Experts

The correct Answer is:
D
When the coin falls, the block moves upwards. Hence l decreases, h will also decrease because when the coin is in the water it will displace equal volume of water, whereas when it is on the block an equal weight of water is displaced .
