Match List - I with List - II.
List - I
(A)
Electric field inside (distance $\displaystyle \mathrm{r}>0$ from center) of a uniformly charged spherical shell with surface charge density $\displaystyle \sigma$, and radius R.
(B)
Electric field at distance $\displaystyle \mathrm{r}>0$ from a uniformly charged infinite plane sheet with surface charge density $\displaystyle \sigma$.
(C)
Electric field outside (distance $\displaystyle \mathrm{r}>0$ from center) of a uniformly charged spherical shell with surface charge density $\displaystyle \sigma$, and radius R.
(D)
Electric field between $\displaystyle 2$ oppositely charged infinite plane parallel sheets with uniform surface charge density $\displaystyle \sigma$.
List - II
(I)
