The electric field in a region of space is given as \(\vec{E}=(5\,\text{N C}^{-1})x\hat{i}\). Consider point \(A\) on the \(y\)-axis at \(y=5\,\text{m}\) and point \(B\) on the \(x\)-axis at \(x=2\,\text{m}\). If the potentials at points \(A\) and \(B\) are \(V_A\) and \(V_B\) respectively, then \((V_B-V_A)\) is
