Answer:
For outer points of shell
Now for inner point of shell
Explanation:
As we know that out side the shell electric potential is given as
inside the shell the electric potential is given as
now we know the relation between electric potential and electric field as
so we can say for outer points of the shell
Now for inner point again we can use the same
