Question

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

Answer 1

Correct Answer - D
As the block moves up with the fall of coin, l decreases, similarly h will also decrease because when the coin is in water, it displaces water equal to equal to its own volume only.
