Correct Answer

A. रेखीय आवेश घनत्वLinear 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।

Explanation opens after your attempt
Correct Answer

B. छल्ले की पूरी परिधि परOn the whole circumference of the ring

Step 1

Concept

A ring is like a closed line.

Step 2

Why this answer is correct

In continuous distribution charge is treated as spread over the circumference.

Step 3

Exam Tip

In exams connect a ring with linear distribution. चरण 1: छल्ला एक बंद रेखा जैसा होता है। चरण 2: सतत वितरण में आवेश पूरी परिधि पर फैला माना जाता है। चरण 3: परीक्षा में छल्ले को रेखीय वितरण से जोड़ें।
