A solid metallic sphere has a charge +3Q. Concentric with this sphere is a conducting spherical shell having charge –Q. The radius of the sphere is a and that of the spherical shell is b(b>a). What is the electric field at a distance r (a < r < b) from the center?
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Electric field at a distance r is only due to sphere because electrice field due to shell inside it is always zero. Hence electric field
