How does the electric field (E) vary with distance (r) in the following cases?
i. Uniformly charged spherical shell
ii. Uniformly charged solid sphere.
iii. Uniformly charged plane sheet of large size.
Also plot a graph between E and r in each case.

Text Solution

Verified by Experts

i. Outside `alpha 1/r^(2)," on surface "=1/r^(2)," inside =zero"`
ii. On the surface `=1/r^(2)," inside "alpha r`
iii. Constant `E=sigma/(2 epsi_(0)), " independent of r"`
