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 center of spheres 1, 2 and 3 are $$E_1 , E_2$$ and $$E_3$$ respectively, then

A

$$E_1 > E_2 > E_3$$

B

$$E_3 > E_1 > E_2$$

C

$$E_2 > E_1 > E_3$$

D

$$E_3 > E_2 > E_1$$
