A point charge \(q\) is placed at origin. Let \(\mathbf{E}_{A^{\prime}} \mathbf{E}_B\) and \(\mathbf{E}_C\) be the electric fields at three points \(A\) \((1,2,3), B(1,1,-1)\) and \(C(2,2,2)\) respectively due to the charge \(q\). Then, the relation between them is
1. \(\mathbf{E}_A \perp \mathbf{E}_B\)
2. \(\mathbf{E}_A \| \mathbf{E}_C\)
3. \(\left|\mathbf{E}_B\right|=4\left|\mathbf{E}_C\right|\)
4. \(\left|\mathbf{E}_B\right|=8\left|\mathbf{E}_C\right|\)
