यदि समान रेखीय घनत्व शून्य है और लंबाई शून्य नहीं है तो कुल आवेश क्या होगा?

If uniform linear density is zero and length is non-zero what is total charge?

Explanation opens after your attempt
Correct Answer

A. शून्य / Zero

Step 1

Concept

Total charge equals linear density multiplied by length.

Step 2

Why this answer is correct

If density is zero the product is zero.

Step 3

Exam Tip

In exams zero density means no charge per unit length. चरण 1: कुल आवेश रेखीय घनत्व और लंबाई के गुणन से मिलता है। चरण 2: घनत्व शून्य हो तो गुणनफल शून्य होगा। चरण 3: परीक्षा में शून्य घनत्व का अर्थ प्रति इकाई लंबाई कोई आवेश नहीं है।
