Correct Answer

B. पृष्ठीय घनत्व क्योंकि आवेश सतह पर है / Surface density because charge is on surface

Step 1

Concept

The question states that charge is on the surface.

Step 2

Why this answer is correct

Charge spread on a surface uses surface density.

Step 3

Exam Tip

A sphere being three dimensional gives volume density only when charge is spread inside. चरण 1: प्रश्न में आवेश सतह पर बताया गया है। चरण 2: सतह पर फैले आवेश के लिए पृष्ठीय घनत्व उपयोग होता है। चरण 3: गोले का त्रिआयामी होना तभी आयतन घनत्व देगा जब आवेश भीतर फैला हो।
