work done=p.E(cos●2-cos●1)
so p.E(cos90°-cos0°)
w=pE
so p.E(cos90°-cos0°)
w=pE

Answer:
Work Done (W) =pE
Explanation:
The magnitude of the electric dipole is p
The magnitude of electric field is E
Initially dipole makes an angle of and finally it makes with electric field
The initial potential energy of the dipole is
The final potential energy of the dipole is
We know that change in potential energy is work done
