Correct Answer

B. हर बिंदु पर स्थानीय घनत्व शून्य है / Local density is zero at every point

Step 1

Concept

Zero average density can mean total charge is zero.

Step 2

Why this answer is correct

But local density may be positive or negative.

Step 3

Exam Tip

In exams do not treat zero average as zero everywhere. चरण 1: औसत घनत्व शून्य होने से कुल आवेश शून्य हो सकता है। चरण 2: पर स्थानीय घनत्व धन या ऋण हो सकता है। चरण 3: परीक्षा में औसत शून्य को हर जगह शून्य न मानें।
