Question

An electric dipole of moment P is lying along a uniform electric field E. The work done in rotating the dipole by 90&deg; is

Amit Saxena · Answer

(c) Work done in rotating a dipole , =pE(1-cosq) If q = 90&deg;, work done = pE (1- 0) = pE

Rishi Sharma · Answer

Dear Student, Please find below the solution to your problem. Workdone = &Delta;pE pE = &minus;p​E pEf​ = 0 pEi​ = &minus;pE &Delta;pE = pE Thanks and Regards
