Question

What will be the torque acting on the dipole if it is placed parallel to electric field

Answer 1

Answer:

1) The torque acting on an electric dipole placed in an electric field is given by the equation, τ = pE sinθ.

2) When the dipole is placed anti parallel to the field, the angle between p and E is 180 degree.

3) Since sin 180= 0, toque acting on the electric dipole is also zero.
