Question 3:

You basically need to leave one mass as the variable, since it isn't affected. Use the first set of info to solve for it, by creating values for the first mass as well as the distance between them. Then use the conditions to solve for Fg. The value is very close, but I'm assuming your teacher rounded since we have to deal with such large numbers.

I'M NOT DOING ANY MORE QUESTIONS. I NEED TO STUDY FOR BIO. GOOD LUCK.

My handwriting looks so bad when I rush. I'm gonna have to review all this crap for the midterm next week. Good practice for me. Grade 12 is basically grade 11, with little introductions of new concepts/equations.

Mines worse, lol. Yours isn't even messy. You're one of those neat writers who always beats themselves up over there perfectly neat writing, aren't you?

Nah. Writing neat is time consuming on tests. My notes are SEMI-OKAY. And you should really do these questions yourself now. Doing them is good practice.
