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

`l` decreases and `h` increases.

`l` increases and `h` decreases .

Both `l` and `h` increase.

Text Solution

Verified by Experts

The correct Answer is:

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 its own volume only.
