Question

:. The electrostatic force on a small sphere of
charge 0.4 uC due to another small sphere of
charge -0.8 uC in air is 0.2 N. (a) What is the
distance between the two spheres? (b) What is
the force on the second sphere due to the first?​

Answer 1

Explanation:

Both the spheres attracts each other with the same force. Therefore the force on the second sphere due to the first is 0.2 N.
