Electrostatic force between 2small sphere having charge 0.4microcolumb

1.	Electrostatic force between 2small sphere having charge 0.4microcolumbis on another sphere placed in air is 0.2neuton find the distance between the two charged sphere and what is the force on the second sphere due to the first sphere
Answer» The electrostatic force on a SMALL SPHERE of charge 0.4 μC due to ANOTHER small sphere of charge − 0.8 μC in air is 0.2 N. ... The distance between the two spheres is 0.12 m. (B) Both the spheres attract each other with the same force. Therefore, the force on the SECOND sphere due to the first is 0.2 N.
