Given an electric potential of
1 q
V=
4πεο r
find its corresponding electric field vector.
Sol.
Using the concept of potential gradient, we have
È = - V
Since we only have, radial direction (r). Then, the del-operator will be
V =î
ar
By substitution, we get
È = - î-
ar
Evaluating the differential, we, get the following
