A sphere contracts in volume by 0.02% when taken to the bottom of a sea 2km deep. Find the value of bulk modulus of the material of the sphere. Density of sea water `1g//c c,g=10ms^(-2)`.

Explanation

To find the bulk modulus of the material of the sphere, we will follow these steps:

### Step 1: Understand the given data
We know that the sphere contracts in volume by 0.02%. The depth at which this occurs is 2 km. The density of seawater is given as 1 g/cm³, and the acceleration due to gravity (g) is 10 m/s².

### Step 2: Convert the percentage contraction to a decimal
The volume contraction is given as 0.02%. To express this as a decimal, we divide by 100:
