In this video, we tackle Problem 4.4 from Griffiths' Introduction to Electrodynamics, exploring the interaction between a point charge and a neutral atom with polarizability α. Step-by-step, we derive the attractive force between them using electrostatics and the concept of induced dipole moments.
🔹 Topics include:
Induced dipole moment: p = αE
Potential energy of an induced dipole in an external electric field
Derivation of the attractive force: F = −(αq²)/(8π²ϵ₀²r⁵)
Physical interpretation and its dependence on distance r
This video is ideal for students studying polarization, dielectrics, and electrostatics in Griffiths Chapter 4.
