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 1 , E 2 and E 3 respectively, then - P R R/2 Q Sphere 1 P R 2Q Sphere 2 P R 2R 4Q Sphere 3

1. E 1 > E 2 > E 3
2. E 3 > E 1 > E 2
3. E 2 > E 1 > E 3
4. E 3 > E 2 > E 1

Correct answer: E 2 > E 1 > E 3
