8. two +1 C charges are separated by 3000m. What is the magnitude of the electric force between them?

1000 N

Explanation:

The magnitude of the electrostatic force between two charged object is given by

where

k is the Coulomb constant

q1, q2 is the magnitude of the two charges

r is the distance between the two objects

Moreover, the force is:

- Attractive if the two forces have opposite sign

- Repulsive if the two forces have same sign

In this problem:

are the two charges

r = 3000 m is their separation

Therefore, the electric force between the charges is:

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!
