QUESTION:
A point charge \(q\) is situated a large distance \(r\) from a neutral atom of polarizability \(\alpha\). Find the force of attraction between them.
ANSWER:Step 1 of 5
Consider a point charge \(q\) and a neutral atom is separated by a distance \(r\). The polarizability of the atom is \(\alpha\). This is the ability of the atom to form a dipole. We are going to force an attraction between the atom and the point charge. Before that, we should find the electric field due to the dipole formed by the point charge and the atom.
