The electrostatic force of attraction or repulsion is can be found as follows,
let us consider 2 bodies in gravitational field of earth. Let the distance between those two bodies is equal to r meters. The charge on the first body is Q1 and charge on second body is Q2.
By columbs force, <u>F </u><u /><u>α Q1×Q2</u><u>
</u> r²
F=<u>k Q1×Q2 </u> where k-gravitational constant.
<u /> r²
