Question

The electrostatic force on a small sphere of charge 0.4newColoumb due to another small sphere of charge -0.8new Coloumb in air is 0.2newton. What is the distance between two spheres. What is the force on second sphere due to first.

Answer 1

Answer:

(a)The distance between two spheres is 0.12m.

(b)Force on the second sphere due to the first is same,0.2n because the charges in action are same and force is attractive as charges are unlike in nature
