Answer:
Explanation:
Volume of the insulating shell is,
Charge density of the shell is,
Here,
B)
The electric field is
For 0 <r<R the electric field is zero, because the electric field inside the conductor is zero.
C)
For R <r <2R According to gauss law
substitute
D)
The net charge enclosed for each r in this range is positive and the electric field is outward
E)
For r>2R
Charge enclosed is zero, so electric field is zero
