Two identical point charges are placed at the two vertices A and B of an equilateral triangle of side $\displaystyle l$. The magnitude of the electric field at the third vertex P is E. If a hollow conducting sphere of radius ( $\displaystyle l / 4$ ) is placed at P, the magnitude of the electric field at point P now becomes
