Answer 2

I will try to answer your questions in detail. Here is what I found:

- A1. A glass bottle rubbed with paper or silk becomes electrified: 1. positively 2. negatively - The correct answer is 1. positively. When a glass bottle is rubbed with paper or silk, it loses electrons to the paper or silk and becomes positively charged. - A2. To an ebonite rod rubbed with fur, bodies charged with: 1. positive charge 2. negative charge are attracted - The correct answer is 1. positive charge. When an ebonite rod is rubbed with fur, it gains electrons from the fur and becomes negatively charged. Opposite charges attract, so a positively charged body will be attracted to the ebonite rod. - A4. Will electrified bodies interact with each other in space, where there is no air? 1. they will 2. they will not - The correct answer is 1. they will. Electrified bodies can interact with each other through electric forces, which do not depend on the presence of air. Electric forces can act over a distance in a vacuum, as long as there is a difference in electric potential between the bodies. - A5. Near charged bodies, the action of the field ..., and when moving away from them .. 1. weaker ... stronger 2. stronger .. weaker - The correct answer is 2. stronger .. weaker. The electric field strength is proportional to the inverse square of the distance from the source charge. This means that as the distance increases, the field strength decreases, and vice versa.
