Question

HELP PLEASE
Positively charged Object A is brought close to neutral Object B but does not touch it. The two objects begin to attract each other. What is this process called?

grounding

charge polarization

conduction

repulsion

Answer 1

Recall how magnets, when brought close together, either attract or repel. Sides of a magnetic with the same charge repel, while those with the opposite charge attracts.

Imagine your neutral Object from the problem statement. It is made-up of atoms, which have electrons orbiting. These electrons have a negative charge.

As we move the positively charged Object A closer to the neutral object, the charge of Object A begins to attract the electrons of the atoms. This creates a charge dipole within the atom. When the dipoles orient just right, the neutral object becomes charged while under the influence of the positively charged Object A.

These dipoles create a polarization effect.
