A spherical volume contains a uniformaly distributed charge of density `2.0 xx 10^(-4) C /m^(3)`. Find the electric field at a piont inside the volume at a distance 4.0 cm from the centre.

Explanation

To find the electric field at a point inside a uniformly charged non-conducting spherical volume, we can use the formula derived from Gauss's Law. Here’s a step-by-step solution:

### Step 1: Understand the Given Data
We are given:
- Charge density, \( \rho = 2.0 \times 10^{-4} \, \text{C/m}^3 \)
- Distance from the center, \( r = 4.0 \, \text{cm} = 0.04 \, \text{m} \)

### Step 2: Use the Formula for Electric Field Inside a Uniformly Charged Sphere
