307. Problem 28.49 (RHK) An electric dipole consists of charge
|
Solution: Click For PDF Version Magnitude of the dipole moment of charge
Dipole moment is a vector quantity. Its direction is from the negative charge toward the positive charge. In an electric field
Electric field strength E is We next calculate the magnitude of torque on the dipole in the three cases. (a) Electric field vector is parallel to the dipole moment vector. In this case the torque on the dipole will be zero. (b) Electric field vector is at right angle to the dipole moment vector. In this case the magnitude of the torque will be (c) Electric field vector is opposite to the dipole moment vector. In this case the torque on the dipole will be zero. |
