I understand the concept and have successfully (I think) solved the problem using a newton calculator online. I would just like to know how to solve this without a plug and play. Here is what I have
F= (6.67*10^-11) * [(M1*2.00)/(6.40*10^6)^2] = 19.60 N
I arrived at M1 = 6.016*10^24
How can i set this up to solve using algebra?
