Question

An electric dipole having dipole moment p=(3^i^j)mC m is placed in a uniform electric fieldE=(2^i+3^j)×103N C1. Then

द्विध्रुव आघूर्ण p=(3^i^j)mC mवाले एक विद्युत द्विध्रुव को एकसमान विद्युत क्षेत्र E=(2^i+3^j)×103N C1 में रखा जाता है। तब

A
The potential energy of the dipole is –3 J

द्विध्रुव की स्थितिज ऊर्जा –3 J है
