Question

Solve for k.
F = kr

Is the answer k=Fr or k=r/F?

Answer 1

k = F/r

Answer 2

You simply rearrange the equation to get k = F/r

Answer 3

Thanks, guys!

Answer 4

Do you need help rearranging equations?

Answer 5

Why is it F/r and not r/F?

Answer 6

Your original question is:

\[F = kr\]

If we divide both left and right sides of the equal sign by 'r'. F gets divded by r, and the k and r get divded by r. Because there is a 'multiplication' between k and r we are able to cancle the division on the right hand side. Which lives us with:

F/r = k

Answer 7

F=k*r
when we bring r to opposite side it becomes division..
F/r=k

Answer 8

Oh, I see. Ha, I was trying to move the k over, and then the F over. Totally wrong. I understand now. Thanks!
