Question

1. A dipole of dipole moment p placed in an electric field E is rotated by 180 degree.if it was
aligned initially along the field find the work done? urgent pls...no spam​

Answer 1

Answer:

please follow me

Explanation:

Work done due to dipole =W=−pEcosθ where p= dipole moment, E= electric field

Here, W=W

(180)

−W

(0)

=(−pEcos180)−(−pEcos0)=pE+pE=2pE

Ans: (B)
