Question

The above figure shows electric field $E$ at a distance r in any direction from the origin $O$. The electric field $E$ is due to

• A. a charged hollow metallic sphere of radius OP with centre at O
• B. a charged solid metallic sphere of radius OP with centre at O
• C. a uniformly charged non-conducting sphere of radius OP with centre at O
• D. a uniformly charged non-conducting hollow sphere of radius OP with centre at O

Answer 1

Answer: (C)

For a uniformly charged non-conducting sphere the graph between electric field and distance from the centre is given by
