    Two electric dipoles of moment PP and 8P8P are placed in opposite directions on a line at a distance of 2424 cm. The electric field will be zero at the point between the dipoles whose distance from the dipole of moment PP will be x1x_1. When 8P8P is replaced by 27P27P keeping all other quantities the same, the distance x1x_1 now becomes x2x_2. The difference ∣x2−x1∣|x_2 - x_1| is ( All the distances are measured from the centers of the dipole.)
