The electrostatic force on small sphere ...

The electrostatic force on small sphere of charge `0.4 muC` due to another small sphere of charge `- 0.8 muC ` in air is 0.2 N.
What is the force on the second sphere due to the first?

Text Solution

Verified by Experts

Since both spheres exert equal and opposite force on each other hence force on the second sphere due to the first is 0.2 N . This force is attractive in nature , since the spheres have opposite charges
