An electric dipole of moment p is lying along a uniform electric field E. The work done in rotating the dipole by 90^o is

Question

Accepted Answer

Correct answer: A. (a) Work done in deflecting a dipole through an angle 6 is given by W= pE sin d = pE(1- cos ) Since =90^o ∴W= pE(1- cos90^o) or, W= pE .

$An electric dipole of moment p is lying along a uniform electric field E . The work done in rotating the dipole by 9 0^{o} is$
