Question

How would you solve this type of problem?

kMn
F= - ____
d^2
solve the equation for M

Answer 1

`M=-(d^2F)/(kn)`

Please look at what I assumed your equation was:
`F=-(kMn)/(d^2)`.

Explanation:

I'm going to pretend that says:

`F=-(kMn)/(d^2)`.

Please correct me if I'm wrong.

We want to solve for M.

The very first thing I'm going to do is multiply both sides by
`d^2`.

`d^2F=-kMn`

Now I'm going to divide both sides by -kn:

`(d^2F)/(-kn)=(-kMn)/(-kn)`

Simplifying:

`(d^2F)/(-kn)=M`

Sometimes people don't like the negative on bottom; just move it to the center:

`-(d^2F)/(kn)=M`

`M=-(d^2F)/(kn)`
