यदि किसी समान पृष्ठीय वितरण में पृष्ठीय घनत्व दुगुना और क्षेत्रफल आधा हो जाए तो कुल आवेश कैसा होगा?

If surface density doubles and area becomes half in a uniform surface distribution what happens to total charge?

Explanation opens after your attempt
Correct Answer

A. समान रहेगा / It remains same

Step 1

Concept

Total charge equals surface density multiplied by area.

Step 2

Why this answer is correct

Double density and half area balance each other.

Step 3

Exam Tip

Therefore total charge remains same. चरण 1: कुल आवेश पृष्ठीय घनत्व और क्षेत्रफल के गुणन से मिलता है। चरण 2: दुगुना घनत्व और आधा क्षेत्रफल एक दूसरे को संतुलित करते हैं। चरण 3: इसलिए कुल आवेश समान रहेगा।
