Two charged particles are placed at a distance 1.0 cm apart. What is the minimum possible magnitude of the electric force acting o each charge?

Text Solution

Verified by Experts

`Minimum charge on body is equal to the charge of electron =1.6xx10^-19C, `
` r=1.0cm=10^-2m `
` F=(9xx10^9xx(1.6xx10^-19)^2)/(10^-2)^2 `
` =2.3xx10^-24N.`
