What is the force between two small charged spheres having charges of `2 xx 10^(-7)C` and `3 xx 10^(-7)` C placed 30 cm apart in air ?

Text Solution

Verified by Experts

`F = k(q_(1)q_(2))/(r^(2))`
`F = (9 xx 10^(9))(2 xx 10^(-7))(3 xx 10^(-7))/(0.3)^(2)`
`F = 6 xx 10^(-3)` N
Here, two given charges are like charges and so above force is repulsive.
