We know that E = -dV/dr
so for approximate calculations
electric field at a point can be written as
E = -del(V)/del(r) where del(V) is the potential drop in the vicinity of the point in distance del(r)
a. at point g
del(V) = 2V
del(r) = 1.7 + 0.65
E = 2/2.35 = 0.851 V/cm
b. at point h
its inside a conductor with constant potential, so, E = 0 V/cm
c. at point i
its inside a conductor with constant potential, so, E = 0 V/cm
d. at point j
del(V) = 2V
del(r) = 0.6 + 0.5
E = 2/1.1 = 1.818 V/cm
e. at point k
del(V) = 2V
del(r) = 0.6 + 1.5
E = 2/2.1 = 0.952 V/cm
f. at point l
del(V) = 2V
del(r) = 1.5 + 0.6
E = 2/2.1 = 0.952 V/cm
