If `E=2r^(2)` then find V(r)

Explanation

To find the electric potential \( V(r) \) given the electric field \( E = 2r^2 \), we can follow these steps:

### Step 1: Understand the relationship between electric field and potential
The electric field \( E \) is related to the electric potential \( V \) by the equation:
\[ E = -\frac{dV}{dr} \]
This means that the electric field is the negative gradient of the electric potential.
