v = 4.8 10⁻⁴ m / s

Explanation:

To solve this exercise we can use the concepts of energy. In this case the potential energy is transformed into kinetic energy

U = K

q V = ½ m v²

v = $$\sqrt { \frac{2qV}{m} }$$

in the exercise they indicate the value of the charge q₁ = 1 pC = 1 10⁻¹² C

let’s calculate

v = $$\sqrt{ \frac{2 \ 1 \ 10^{-12} 120 \ 10^3}{500 ^{2} }$$

v = 4.8 10⁻⁴ m / s
