The gravitational potential due to a mass distrubution is given by `V=(8x)/(x^(2)+p^(2))`. Find gravitational field at x = p.

Explanation

To find the gravitational field \( E \) at \( x = p \) given the gravitational potential \( V = \frac{8x}{x^2 + p^2} \), we will follow these steps:

### Step 1: Understand the relationship between gravitational field and potential
The gravitational field \( E \) is related to the gravitational potential \( V \) by the formula:
\[ E = -\frac{dV}{dx} \]
