Question:
A long, hollow conducting cylinder is kept coaxially inside another long, hollow conducting cylinder of larger radius. Both the cylinders are initially electrically neutral.
A long, hollow conducting cylinder is kept coaxially inside another long, hollow conducting cylinder of larger radius. Both the cylinders are initially electrically neutral.
Show Hint
For conductors, electric field inside the material is always zero.

- a potential difference appears between the two cylinders when a charge density is given to the inner cylinder.
- a potential difference appears between the two cylinders when a charge density is given to the outer cylinder.
- no potential difference appears when a uniform line charge is kept along the axis of the cylinders.
- no potential difference appears when same charge density is given to both the cylinders.
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: If charge is given to the inner cylinder, electric field exists in the region between the cylinders.
Step 2: This produces a potential difference between the two cylinders.
Step 3: Charging only the outer cylinder does not create an electric field inside it.
