एक समान आवेशित छल्ले के केंद्र पर विद्युत विभव शून्य नहीं हो सकता जबकि क्षेत्र शून्य हो सकता है। इसका कारण क्या है?

At the centre of a uniformly charged ring potential may be non-zero while field is zero. What is the reason?

Explanation opens after your attempt
Correct Answer

A. विभव अदिश है और क्षेत्र सदिश है / Potential is scalar and field is vector

Step 1

Concept

Opposite field components cancel by symmetry.

Step 2

Why this answer is correct

Potential is scalar so contributions generally add.

Step 3

Exam Tip

In exams keep the nature of field and potential separate. चरण 1: क्षेत्र के विपरीत घटक सममिति से रद्द हो जाते हैं। चरण 2: विभव अदिश होने से योगदान सामान्यतः जुड़ते हैं। चरण 3: परीक्षा में क्षेत्र और विभव की प्रकृति अलग रखें।
