Polarizability is defined by the relation p =q5 = aĒext, where a is polarizability and Ēextis the external electric field that induces thepolarization. We can obtain an estimate ofa for a typical neutral atom by making a fewsimple assumptions:1: Ēext is evaluated at the center of thedipole, i.e., the original location of theunpolarized atom.2: The separation distance s is on the or-der of atomic dimensions - use s = 2R,where R 1 x 10-10 m is on the orderof an atomic radius. This is a reasonablemaximum estimate, as " polarization" be-yond an atomic diameter typically re-sults in ionization of the atom.3: Ēext + Edip = 0 at the center of the in-duced dipole.Based on these assumptions, calculate anorder-of-magnitude estimate for a. Since weare only interested in order of magnitude, youwill obtain an answer of the form a 1x 104.What is the value of A?

We take the three assumption of given question

Polarizability is defined by the relation p = = aĒext, where a is polarizability and Ēext he external electric field that induces the arization. We can obtain an estimate of or a typical neutral atom by making a few ple assumptions: =Ēext is evaluated at the center of the dipole, i.e., the original location of the unnolarized atom.
