In a gravitational field, the gravitational potential is given by,...

Gravitational field intensity (=\frac{-\partial V}{\partial x} \hat{i}+\frac{-\partial V}{\partial y} \hat{j}+\frac{-\partial V}{\partial x} \widehat{k}) where V is gravitational potential (\Rightarrow) Gravitational field intensity (=\frac{-\partial}{\partial x}\left[\frac{-K}{x}\right]=\frac{-K}{x^2} \hat{i}) at $(2,0,3)$ (\overrightarrow{E_G}=\frac{-K}{2^2}=\frac{-K}{4} \hat{i})
