यदि किसी पतले छल्ले पर आवेश परिधि के साथ फैला है तो किस घनत्व का उपयोग सबसे उचित है?

If charge on a thin ring is spread along the circumference which density is most suitable?

Explanation opens after your attempt
Correct Answer

A. रेखीय आवेश घनत्व / Linear charge density

Step 1

Concept

Charge on a thin ring is spread along circumference which is like a line.

Step 2

Why this answer is correct

Such spread uses charge per unit length.

Step 3

Exam Tip

Therefore linear charge density is most suitable. चरण 1: पतले छल्ले का आवेश परिधि यानी रेखा जैसे मार्ग पर फैला है। चरण 2: ऐसे फैलाव में प्रति इकाई लंबाई आवेश लिया जाता है। चरण 3: इसलिए रेखीय आवेश घनत्व सबसे उचित है।
