repulsive electric fields are stronger than attractive electric fields


B.


the distance each object is from the electric field of the other

Answer 2

I think it's A and C, am I correct?

Answer 3

Are you familiar with Coulomb's Law?

Answer 4

nope, can you please explain?

Answer 5

Coulomb's law states that:

The magnitude of the electrostatic force of interaction between two point charges is directly proportional to the scalar multiplication of the magnitudes of charges and inversely proportional to the square of the distance between them.
$$
|\mathbf F|=k_e{|q_1q_2|\over r^2}\qquad
$$

The force between the two charges is dependent on distance (inverse square) and the magnitude of their charges.

That's it.

Answer 6

so B is one of the answers?

Answer 7

yes!

Answer 8

The greater the charge the greater the electric field of the charge:
$$
|\boldsymbol{E}|={1\over4\pi\varepsilon_0}{|q|\over r^2}
$$

The farther away you are from the charge the smaller the electric field.

Answer 9

A?

Answer 10

Note that the force on a charge \(q_2\) due to and electric field E is
$$
F=q_2\times E
$$

So distance and strength of the electric fields are important factors

Answer 11

I meant B AND C

Answer 12
