Charges Q, 2Q and 4Q are uniformly distributed in three dielectric solid spheres 1, 2 and 3 of radii R/2, R and 2R respectively, as shown in figure. If magnitudes of the electric fields at point P at a distance R from the centre of spheres 1, 2 and 3 are E, E and E3 respectively, then P: Sphere 1 (A) E > E> E3 R/2 2Q R Sphere 2 (A) E3> E > E 4Q (C) E > E > E3 P R Sphere 3 2R (D) E3 > E > E
