Q1. An electron and a neutral carbon atom are firstly 2.2 × 10^(-6) m apart, and there are no other particles in the vicinity. The mass of the electron is m = 9.11 × 10^(-31)kg. The polarizability of the carbon atom has been measured to be α = 1.96 × 10^ (-40)C • m/(N/C). Suppose that k = 1 4π (E) 0 = 9 × 10^9 N • m^2 /C^ 2.
Calculate the initial magnitude of the acceleration of the electron.
