When a positively charged sphere is brought near a neutral, uncharged sphere, the following happens:
- The positive charges in the charged sphere will create an electrostatic force on the charges within the neutral sphere.
- The positive charges in the neutral sphere will be attracted to the positive charges in the charged sphere.
- The negative charges in the neutral sphere will be repelled by the positive charges in the charged sphere.
- As a result, the electrons within the neutral sphere will be pulled towards the positively charged sphere. This means the neutral sphere will gain extra electrons, becoming negatively charged.
- The neutral sphere will now have an excess of negative charges and a deficit of positive charges, making it negatively charged. The original positive charge sphere will have transferred some of its charge to the neutral sphere.
Therefore, the neutral sphere will become negatively charged as electrons are attracted to the positive sphere. The amount of charge transferred depends on the strength of the original charged sphere and the proximity of the two spheres.
