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 some time the coin falls into the water. Then

A

l decreases

B

h decreases

C

l increases

D

h increases

Text Solution

Verified by Experts

The correct Answer is:
A, B
When coil falls in water, upthrust on the block (which is equal to the weight of the block +coin) decreases.As a result, volume of water displaced will decrease and hence l decreases. And h also decreases because of less immersed portion of the wooden block than wooden block with coin.
