**********   help pls. ;'(  IS THIS THE RIGHT ANSWER?   How would you expect the force of attraction between positive ion A and negative ion B be affected by the following changes???

fanduekisses · Answer

the radii of both A and B are simultaneously doubled -----> does that mean the force of attraction decreases by 1/16????

anonymous · Answer

is this chemistry?

fanduekisses · Answer

yes, hehe.

anonymous · Answer

this should be posted in chemistry section then..but anyways,
how do you know it is 1/16, were you given a formula?

fanduekisses · Answer

$$\frac{ (q_{1} \times q_{2}) }{ d^2}$$

fanduekisses · Answer

distance increased so force decreased.

fanduekisses · Answer

2 times 2 = 4 then 4 squared 16... so it decreases by 1/16?

anonymous · Answer

F = k q1 q2 / d^2 exactly what i am thinking :P

If you double the distance BETWEEN those two atoms, wouldn't be 1/4?

fanduekisses · Answer

Why does it say "the radii of both A and B are simultaneously doubled" ? I thought it meant like the radii of both so 2 * 2

fanduekisses · Answer

wait radii is the plural of radius? lol xD

anonymous · Answer

oh it says "radii of BOTH" 
so  i think you are right then

sorry i keep missing important parts of the question -.-
