Answer to Question #184370 in Electric Circuits for Yasmine abdelaal

Question

 Find the magnitude of the electrical force and the

gravitational force between the electron and the proton in the

atom. The average distance between the two particles is 0.53 A

Answer 1

$F_e = \frac{q_eq_p}{4πε_0R^2} \\ = \frac{(1.6 \times 10^{-19})^2}{4π(8.85 \times 10^{-12})(0.53 \times 10^{-10})^2} \\ = \frac{2.56 \times 10^{-38}}{(1.112 \times 10^{-10})(0.2809 \times 10^{-20})} \\ = \frac{2.56 \times 10^{-38}}{3.1236 \times 10^{-31}} \\ = 8.2 \times 10^{-8} \;N$
