An electric dipole of moment p . is lying along a uniform electric field E The work done in rotating the dipole through 90^ is [ 0^ = 90^ =0, 0^ = 90^ =1 ]
Options
- ApE
- B2 pE
- CpE / 2
- D3 p p
Correct answer
A. pE
Step-by-step solution
Work done = pE aligned & pE =- p E & pE _ f =0 & pE _ i =- pE & pE = pE aligned
