A wooden block with a coin placed on its top, floats in water as shown in figure.

The distance l and h are shown in the figure. After sometime, 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
The block moves up, so l decreases. When the coin is in water, it displaces an equal volume of water only. So h also decreases.
