The gravitational field due to a mass distribution is given by `l=kx^(-3//2)` in x-direction, where k is a positive constant. Taking potential to be zero at infinity, find its value at a distance x.

Explanation

To find the gravitational potential \( V \) at a distance \( x \) given the gravitational field \( E = kx^{-3/2} \), we can 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 equation:
\[ E = -\frac{dV}{dx} \]
This means that the gravitational field is the negative gradient of the potential.
