A rubber ball of bulk modulus `B` is taken to a depth h of a liquid of density `rho`. Find the fractional change in the radius of the ball.

Explanation

To find the fractional change in the radius of a rubber ball when it is submerged to a depth \( h \) in a liquid of density \( \rho \), we can follow these steps:

### Step 1: Understand the concept of Bulk Modulus
The bulk modulus \( B \) of a material is defined as the ratio of the change in pressure to the fractional change in volume. Mathematically, it is expressed as:

\[ B = -\frac{P}{\frac{\Delta V}{V}} \]
