Two point charged bodies `q_(1) = 3 muC`, and `q_(2) = 4 muC` are separated by 2 m in air. Find the magnitude of electrostatic force between them.

Text Solution

Verified by Experts

Given `q_(1) = 3 muC = 3xx 10^(-6)C`
`q_(2) = 4 muC = 4 xx 10^(-6)C`
`r = 2 m`
Medium is air
`:.` Force , `F = (1)/(4piepsi_(0)) (q_(1)q_(2))/(r^(2))`
`= (9 xx 10^(9) xx 3 xx 10^(-6) xx 4 xx 10^(-6))/((2)^(2))`
`= (9 xx 10^(9) xx 3 xx 10^(-6) xx 4 xx 10^(-6))/(4) = 27 xx 10^(-3) N = 27 mN`
