By experiment, determine what makes a force attractive or repulsive. Describe your experiments and observations with some examples. 4. What evidence do you see that Newton's third law applies to electrostatic forces

he combs are brought closer, each one has to move, therefore a force must be applied to each one, and the only force is electrostatic. force must have the same magnitude in each one and in the opposite direction; this description is equivalent to Newton's third law.

Explanation:

A very simple experiment that we can do is to rub a brush or plastic comb with a piece of paper, this creates some electrical charges in the comb, we hang the comb by a thread.

We take another comb and we form it with the same paper, when we bring the combs closer, we see that they repel each other, this is proof that the electrical charges created are of the same type.  

If now we rub the comb with another material, for example plastic, and bring it closer to the comb that is hanging, we see that they are approaching, therefore, it is proven that the load created from another type

With these two simple experiments it can be proved that electric charges are of two types, which are called positive and negative.  

4. In the previous experiment we see that when the combs are brought closer, each one has to move, therefore a force must be applied to each one, and the only force is electrostatic. If we observe carefully we see that the breaking of the combs is the same, therefore the force must have the same magnitude in each one and in the opposite direction; this description is equivalent to Newton's third law.

The distance between Earth and Sun is about 0.0000038 times 
the distance to the next nearest star.

(The next nearest star is about 265,300 times as far from us as 
the sun is.) 

The distance between Earth and Sun is about 0.000000000000000000068 
times the distance to the next nearest galaxy.

(The next nearest galaxy is about 14,700,000,000,000,000,000 times 
as far from us as the sun is.) hope this helped.
