`v = 2x^(2) + 3y^(2) + zx`
Find gravitational at a point (x ,y ,z) .

Explanation

To find the gravitational field \(\mathbf{E}\) at a point \((x, y, z)\) given the gravitational potential \(V = 2x^2 + 3y^2 + zx\), we will follow these steps:

### Step 1: Understand the relationship between gravitational potential and gravitational field
The gravitational field \(\mathbf{E}\) is related to the gravitational potential \(V\) by the equation:
\[ \mathbf{E} = -\nabla V \]
where \(\nabla\) (nabla) is the gradient operator.
