Answer 1

do you know what coulomb's law is?

Answer 2

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)

Answer 3

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

Answer 4

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

Answer 5

I know it's not B.

Answer 6

ok so initial distance is lets say d

now final distance becomes 2d... so plug in and see how what happens.. and compare !

Answer 7

okay so mine increased by 8

Answer 8

* 8 times

Answer 9

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

Answer 10
