## AngelicDragon 2 years ago HELP!!!! According to Coulomb's Law, if the distance between the nucleus and electron were doubled, the force would be A. 1/4 as much. B. 1/2 as much. C. two times as much. D. four times as much.

1. Mashy

do you know what coulomb's law is?

2. AngelicDragon

Yeah but I got this one wrong on my test and the stupid thing explained everything but this one. (It even explained the correct answers)

3. Mashy

ok .. state the coloumb's law.. ! in equation form

4. AngelicDragon

\[f_{e}= (Kq_{1}q_{2})/d^{2}\]

5. AngelicDragon

I know it's not B.

6. Mashy

ok so initial distance is lets say d now final distance becomes 2d... so plug in and see how what happens.. and compare !

7. AngelicDragon

okay so mine increased by 8

8. AngelicDragon

* 8 times

9. AngelicDragon

I'm pretty sure it wasn't supposed to increase by that much

10. AngelicDragon

um…scratch that I put in wrong the second time

11. AngelicDragon

It was 1/4 as much

12. AngelicDragon

@Mashy Thanks!!! =) (= <3

13. Mashy

ok .. yea thats right :D
