यदि समान पृष्ठीय घनत्व आधा और क्षेत्रफल दोगुना हो जाए तो कुल आवेश क्या होगा?

If uniform surface density becomes half and area doubles 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

If density halves and area doubles the product remains same.

Step 3

Exam Tip

In exams check both ratio and product. चरण 1: कुल आवेश पृष्ठीय घनत्व और क्षेत्रफल के गुणन से मिलता है। चरण 2: घनत्व आधा और क्षेत्रफल दोगुना होने पर गुणनफल समान रहता है। चरण 3: परीक्षा में अनुपात और गुणनफल दोनों जाँचें।
