Answer:
Let the length of AB and BC is P
And
Radius of AB is 2r
Radius of BC is r
R
AB
=
π(2r)
2
ρP
=
4πr
2
ρP
And
R
BC
=
πr
2
ρP
Therefore
R
AB
=
4
R
BC
Potential across AB
V
AB
=E[
R
AB
+R
BC
R
AB
]
=E[
5R
AB
R
AB
]=
5
E
Potential across BC
V
BC
=E−
5
E
=
5
4E
Potential gradient of AB=
5P
E
Potential gradient across BC=
5P
4E
Now the ratio of potential gradient =
4E/5P
E/5P
=1:4
