The electric force on the electron due to the nucleus is 9.24 × [tex]10^{-9} N[/tex]
The essential quality that a material thing must have in order to interact electromagnetically with its environment is a charge. Coulomb's law asserts that the force of attraction, as well as repulsion between two charges q1 as well as q2 separated by a distance r, determines the electric force separating charges at rest (branch of electrostatics).
F = K [tex]q_{1} q_{2} / r^{2}[/tex]
Given data:
n = 40
r = 1 nm
Charge (q) can be determined by the formula:
q = ne
q = 40 × 1.6 × [tex]10^{-19}[/tex] = 64 × [tex]10^{-19}[/tex] C
Electric charge can be calculated as by using the formula:
F = K [tex]q_{1} q_{2} / r^{2}[/tex]
F = 9 × [tex]10^{9}[/tex] × 64 × [tex]10^{-19}[/tex] × 1.6 × [tex]10^{-19}[/tex] / [tex]10^{-18}[/tex]
F = 9.24 × [tex]10^{-9} N[/tex]
Therefore, the electric force on the electron due to the nucleus is 9.24 × [tex]10^{-9} N[/tex].
