I want to be sure I'm using the right formula for this question:

Calculate the electric force between 2 electrons that are 5.3 x 10^-11 m apart (electron charge = -1.6 x 10^-19 C)
I'm using the equation for Coulomb's Law: F = K (q1 q2)/d^2

(-1.6 x 10^-19)(-1.6 x 10^-19) /
5.3 x 10^-11 m ^2
Am I even on the right track???????

You are on the right track but you left out k which is 9*10^9 and you must square the distance

(9*10^9)(-1.6 x 10^-19)(-1.6 x 10^-19) /
(5.3 x 10^-11)^2

Yes, you are on the right track! The equation you are using is indeed Coulomb's Law, which relates the electric force between two charged particles to their charges and the distance between them.

To calculate the electric force between two electrons, you first need to plug in the values into the equation correctly. Let's break it down step by step.

1. Identify the given values:
q1 = charge of the first electron = -1.6 x 10^-19 C
q2 = charge of the second electron = -1.6 x 10^-19 C
d = distance between the electrons = 5.3 x 10^-11 m

2. Substitute the values into the equation:
F = K * (q1 * q2) / d^2

K is the electrostatic constant and has a value of approximately 8.99 x 10^9 Nm^2/C^2.

Plugging in the values:
F = (8.99 x 10^9 Nm^2/C^2) * [(-1.6 x 10^-19 C) * (-1.6 x 10^-19 C)] / (5.3 x 10^-11 m)^2

3. Simplify the equation and calculate:
F = (8.99 x 10^9 Nm^2/C^2) * (2.56 x 10^-38 C^2) / (2.809 x 10^-21 m^2)
F = 9.103 x 10^-9 N

Therefore, the electric force between the two electrons is approximately 9.103 x 10^-9 Newtons.

Remember to always pay attention to the units and ensure that they are consistent throughout the calculation.
