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:

i don't understand. explain it clearly

i had this question and the answer was 3.15 miles.

martina travels from school to her mom's office. from there, she walks to school. after school, she walks to the library and then to a friends house before finally ending back at home. find martina's total distance traveled.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles
