SUMMARY

The discussion focuses on the calculations of electrostatic forces and electric fields involving point charges and parallel plates. The electrostatic force between two charges is derived using Coulomb's law, resulting in a new force of 1.8 x 10^-2 N after adjusting for changes in charge and distance. Participants also calculated the electric field at a point between two charges and the final speed of an electron in an electric field, emphasizing the importance of using the correct formulas, such as qV = 1/2 mv². Key corrections were made regarding the application of these formulas and the significance of distance in energy calculations.

(1.6 x 10^ -19 C) (4.5 x 10^3 V) = 1/2 x 9.1 x 10^-31 x v^2
v=\sqrt{2(1.6*10^-19 * 4.5*10^3)/9.1*10^31}

(1.6 x 10^-19 C) (4.5 x 10^3 V) = 1/2 x 9.1 x 10^-31 x v^2
v=\sqrt{2(1.6*10^{-19} * 4.5*10^3)/(9.1*10^{31})}
i think you get this part rite, check your arithmatic...
