The gravitational field due to a mass distribution is given by `E=-K//x^3` in x-direction. Taking the gravitational potential to be zero at infinity, find its value at a distance `x`.

Explanation

To find the gravitational potential \( V \) at a distance \( x \) from a mass distribution given the gravitational field \( E = -\frac{K}{x^3} \), we can follow these steps:

### Step 1: Understand the relationship between gravitational field and potential
The relationship between the gravitational field \( E \) and the gravitational potential \( V \) is given by:
\[ dV = -E \, dx \]
This means that the change in potential \( dV \) is equal to the negative of the gravitational field \( E \) multiplied by the differential distance \( dx \).
