Electrostatics Question 230
Question: A solid metallic sphere has a charge . Concentric with this sphere is a conducting spherical shell having charge . The radius of the sphere is and that of the spherical shell is . What is the electric field at a distance from the centre [MP PMT 1995]
Options:
A)
B)
C)
D)
Show Answer
Answer:
Correct Answer: C
Solution:
Electric field at a distance R is only due to sphere because electric field due to shell inside it is always zero.
Hence electric field =
