**Using the formula F = kQq/R2 sketch graphs between**

a. F and Q (k,q, and R are constant)

b. F and R (Q,q and k are constant)

c. Q and R (k,q and F are constant)

a. F and Q (k,q, and R are constant)

b. F and R (Q,q and k are constant)

c. Q and R (k,q and F are constant)

I think i did it correctly but I'm not quite sure.

a) I wrote that F is

**directly proportional**to Q so i guess its Direct Variation graph.

b) Is 1 / R^2

**inversely proportiona**l? And is the graph the same as y= 1/x or should it be y=SQUAREROOT of 1/x but then it wouldn't make sense?

c) i got it so that it's R = SQUAREROOT of Q so it's

*direct root*graph?

I hope that's correct! Can anybody double check?
