    Variable
In summary, to solve for m1 in the equation f= Gm1m2 / r squared, you can use simple algebra and the property that for any real numbers a and k, both not equal to zero, a*(1/k)*k=a. By rearranging the equation, you can isolate m1 and solve for it.

where is your attempt?

work must be shown b4 we can help, thanks!
 
  • #3
I have no idea how to solve it.
 
  • #4
here's a hint: Gm1m2 is simply G times m1 times m2

now what would your steps be?

Are you kidding? This is very simple algebra. Do you know that for any real numbers a and k, both of them not equal to zero, a*(1/k)*k=a ?

You want m1, but you have it on the right-hand side being multiplied by Gm2/(r^2)

(the digits shown in your equation must be assumed as subscripts; if we use TEX or LaTex, we could show that more clearly)

Or by using these tags
- Subscript
- Superscript

The corresponding end tags have a forward slash (/) in front of sub and sup.

Examples: m1 m2
