the torque acting on an electric dipole of dipole moment p placed parallel to the electric field the field E will be
Answers
Explanation:
The torque acting on an electric dipole placed in an electric field is given by the equation, τ = pE sinθ. When the dipole is placed anti parallel to the field, the angle between p and E is 180 degree. Since sin 180= 0, toque acting on the electric dipole is also zero
Torque acting on the dipole is ζ = pE sinΘ
Explanation:
- Torque is the rotation produced in an electric dipole when it is placed in the Electric field. It is given as the vector product of dipole moment of dipole and applied electric field
- Torque is given as ζ = p E sinΘ
where, p= dipole moment of the dipole
E = electric field in which dipole is placed
Θ = angle by which dipole is inclined to the electric field
When Θ = 0° , dipole and electric field are parallel to each other
ζ =p E sin 0° ( sin 0°= 0)
ζ = 0 ( no rotation will be there)
When Θ = 90° , dipole and electric field are perpendicular to each other
ζ = p E sin 90° ( sin 90° = 1)
ζ = p E (maximum torque)
When Θ = 180° , dipole and electric field are anti parallel to each other
ζ = p E sin 180° (sin 180° = 0)
ζ = 0 (minimum torque hence no rotation)
