द्विध्रुव को समांतर स्थिति से विपरीत स्थिति तक घुमाने में बाहरी कार्य कितना होगा यदि द्विध्रुव आघूर्ण दो और क्षेत्र सात है?

What external work is needed to rotate a dipole from parallel to opposite position if dipole moment is two and field is seven?

Explanation opens after your attempt
Correct Answer

B. अट्ठाईस जूल / Twenty eight joule

Step 1

Concept

Parallel energy is negative dipole moment times field.

Step 2

Why this answer is correct

Opposite energy is positive dipole moment times field.

Step 3

Exam Tip

Increase is two times two times seven which is twenty eight joule. चरण 1: समांतर ऊर्जा ऋण द्विध्रुव आघूर्ण गुणा क्षेत्र होती है। चरण 2: विपरीत ऊर्जा धन द्विध्रुव आघूर्ण गुणा क्षेत्र होती है। चरण 3: ऊर्जा वृद्धि दो गुणा दो गुणा सात यानी अट्ठाईस जूल है।
