explain potential energy of a dipole in external Field.​

Answer 1

$\huge{\underline{\pmb{\pink{Answer}}}}$Potential energy of a dipole in an external field

Electric potential energy of an Electric dipole in dipole from zero energy position to the desired position (The zero enrgy position to be one when the dipole When an electric dipole of dipole moment p is on it such that P=

This torque tends to rotate the dipole let dW the small amount of work done. turning the dipole through an angle dθ

W is the work done in turning the dipole from 0

Answer 2

Answer:

dipole is an external field experience a torque which tries to align it in direction of electric field.
