Constant Electric Field in a Vacuum

Problem 3.1

Calculate the ratio of the electrostatic to gravitational interaction forces between two electrons, between two protons. At what value of the specific charge \(q / m\) of a particle would these forces become equal (in their absolute values) in the case of interaction of identical particles?

Reveal Answer
 3.1. The ratio Fel/Fgr is equal to 4⋅1042 and 1⋅1036 respectively; a/m=0.86⋅10−10C/kg\begin{aligned} &\text { 3.1. The ratio } F_{e l} / F_{g r} \text { is equal to } 4 \cdot 10^{42} \text { and } 1 \cdot 10^{36} \text { respectively; }\\ &a / m=0.86 \cdot 10^{-10} \mathrm{C} / \mathrm{kg} \end{aligned}
