Answer 2

\(\sf F_g=G\huge \frac{m_1m_2}{r^2}\\ Now~if~distance~between~the~two~objects~is~constant~then~we~can~say~that\\~\\~\\ F_g\propto m_1m_2\)

Let the initial gravitational force be F and gravitational force after the masses are doubled be \(\sf F'\)

So, \(\huge \sf \frac{F}{F'}=\frac{m_1\times m_2}{2m_1\times 2m_2}=\frac{1}{4}\\ \Rightarrow F'=4F\)

Answer 3

you probably didn't notice, but you posted your \(\large\sf\color{blue}{\underline{\href{ http:///openstudy.com/study#/groups/physics}{Physics}}}\) question in the Chemistry section.
Next time when you ask a question, check if you're in the right section :)
