एक समान पृष्ठीय वितरण में कुल आवेश चौरासी कूलॉम और क्षेत्रफल बारह वर्ग मीटर है। यदि कुल आवेश दोगुना और क्षेत्रफल सात गुना हो जाए तो नया पृष्ठीय घनत्व क्या होगा?

In a uniform surface distribution total charge is eighty four coulomb and area is twelve square metre. If total charge doubles and area becomes seven times what is the new surface density?

Explanation opens after your attempt
Correct Answer

A. दो कूलॉम प्रति वर्ग मीटर / Two coulomb per square metre

Step 1

Concept

New charge becomes one hundred sixty eight coulomb.

Step 2

Why this answer is correct

New area becomes eighty four square metre.

Step 3

Exam Tip

Surface density is one hundred sixty eight divided by eighty four which is two. चरण 1: नया आवेश एक सौ अड़सठ कूलॉम होगा। चरण 2: नया क्षेत्रफल चौरासी वर्ग मीटर होगा। चरण 3: पृष्ठीय घनत्व एक सौ अड़सठ को चौरासी से बाँटकर दो मिलेगा।
