Physics Question from JEE Main 2026 · 22 January, Shift 1

Electric field in a region is given by $\vec{E} = A x\,\hat{i} + B y\,\hat{j}$, where $A = 10 \, \text{V/m}^2$ and $B = 5 \, \text{V/m}^2$. If the electric potential at a point $(10, 20)$ is $500 \, \text{V}$, then the electric potential at origin is _____ V.
