Question

art A

A positively charged non-metal ball A is placed near metal ball B. Prove that if the charge on B is positive but of small magnitude, the balls will be attracted to each other.

A positively charged non-metal ball A is placed near metal ball B. Prove that if the charge on B is positive but of small magnitude, the balls will be attracted to each other.

The positive charges on the sphere B move to the side closer to sphere A, while the negative charges move to the side further away from sphere A. The polarization of charge on A will cause a greater attractive force than the repulsion of the like charges. The negative charges on the sphere A move to the side closer to sphere B, while the positive charges move to the side further away from sphere B. The polarization of charge on A will cause a greater attractive force than the repulsion of the like charges. The positive charges on the sphere B move to the side closer to sphere A, while the negative charges move to the side further away from sphere A.
