Two electrons are separated by a distance of 2.5 times 10^-11m. What is the force of attraction between them?

Question

anonymous · Answer

Coulomb's Law:$$F= \frac{ k|q _{1}||q _{2}| }{ r^2 } $$
Where F is the force between charged objects, q1 and q2 are the charges and r is the distance between the particles.

anonymous · Answer

yes and???

anonymous · Answer

Do you know the charge of each particle,  distance between them? k is a fundamental constant, k = 8.99 * 10^9

anonymous · Answer

the charge of each electron is -1.6 * 10^-19

anonymous · Answer

Ok, so plug all those numbers into the equation I gave you, that will give you the force acting between the particles.

anonymous · Answer

Wait!!! when i plug this in into a graphing calclator. it gives me a long answere
I got 9.216 e^-40

anonymous · Answer

I get 3.69 * 10^-7
Double check your calculations. You are probably making a small error somewhere.

Is this a trick question,  (attraction between like charges......repulsion would be a better word.     Or would it????

radar · Answer

Oh, repels might be suitable.
