किस स्थिति में समान विद्युत क्षेत्र द्विध्रुव को घुमाने की कोशिश नहीं करता?

In which condition does a uniform electric field not try to rotate a dipole?

Explanation opens after your attempt
Correct Answer

B. जब द्विध्रुव आघूर्ण क्षेत्र के समांतर हो / When dipole moment is parallel to the field

Step 1

Concept

The tendency to rotate is measured by torque.

Step 2

Why this answer is correct

In the parallel position, the angle is zero and torque is zero.

Step 3

Exam Tip

Therefore, the field does not try to rotate the dipole in this condition. चरण 1: घुमाने की कोशिश बल आघूर्ण से मापी जाती है। चरण 2: क्षेत्र के समांतर स्थिति में कोण शून्य होता है और बल आघूर्ण शून्य होता है। चरण 3: इसलिए क्षेत्र इस स्थिति में द्विध्रुव को घुमाने की कोशिश नहीं करता।
