Determine whether this system of linear equations is consistent and, if so, find its general solution. Write the solution in vector form.

An object moving in the xy-plane is acted on by a conservative force described by the potential energy function ${\displaystyle U(x,y)=\alpha (\frac{1}{x^2}+\frac{1}{y^2})}$ where ${\displaystyle \alpha }$ is a positive constant. Derivative an expression for the force expressed terms of the unit vectors ${\displaystyle \overrightarrow{i}}$ and ${\displaystyle \overrightarrow{j}}$.
