Two +1 C charges are separated by 3000 m. What is the magnitude of the electric force

¡Hello!

Topic: Electrostatic

For calculate electric force, we can apllicate formula:

F = Electric Force

k = Coulomb Constant = 9x10^9

q = Charges = 1 C

r = Distance = 3000 m

Let's replace according the information, and let's resolve it:

F = 9x10^9 * (1 * 1) / 3000²

F = 9x10^9 * 1 / 9000000

F = 9x10^9 * 1.1111111e-7

F = 1000 N

Result:

The electric force is of 1000 N

Good luck
