Question

potential energy of Dipole placed in uniform electric field
​

Answer 1

Consider a dipole with charges q1 = +q and q2 = -q placed in a uniform electric field as shown in the figure above.

..

. From the above equation, we can see that the potential energy of dipole placed in an external field is zero when the angle Ɵ is equal to 90° or when the dipole makes an angle of 90°.
