Question

An electric dipole consists of a negative charge- located at (0,-) and a positive charge +q located at (0, +3). The dipole moment p is defined as a vector of magnitude qs directed from the negative charge of the dipole to the positive charge of the dipole. (a) Show that the net force exerted by the dipole on a charge +Q located on the r-axis at a distance r from the dipole is given by: s 2 -3/2 F- r (b) Using the binomial theorem, find a first-order approximation for the force found in the previous step in the case where the charge is at a distance that is very large when compared to the separation of the dipole, that is, s 《 r. (Hint: This does not mean making 8-0)

An electric field can induce an electric dipole in a neutral molecule (or atom) by pushing the positive and negative charges inside the molecule in opposite directions. The dipole moment of the induced dipole is directly proportional to the electric field at the molecule. That is, p⃗ =αE⃗ , where p⃗ is the induced dipole moment, α is called the polarizability of the molecule, and E⃗ is the electric field at the molecule. A stronger electric field at the molecule results in a...

Some types of molecules that do not possess an intrinsic electric dipole moment can be given...

Some types of molecules that do not possess an intrinsic electric dipole moment can be given one by an external electric field in a process called charge separation, or polarization. In this process, their internal charge distribution becomes distorted by the field, which results in the region of a molecule on the side in the direction of the field gaining a positive net charge and the region on the other side gaining a negative net charge. Both charges have equal...
