Question

correct me if i'm wrong
question below:

Answer 1

\(\LARGE F=\frac{GM_{1}M_{2}}{R^2}\)

determine what happens to \(F\)

\(M_1\ is\ quadrupled\) , F will also be quadrupled
\(R\ is\ tripled\), F will be 1/9 less
\(M_2\ is\ quadrupled\ and\ R\ is\ doubled\), F will be the same
\(M_1\ is\ doubled\ and\ M_2\ is\ tripled\), F is six times larger
\(M_2 \ is\ doubled\ and\ R\ is\ made\ five\ times\ greater\), F will 2/25 less

am i right?

Answer 2

@wolfe @hartnn @e.mccormick @surjithayer
thanks, brb.

Answer 3

"F will be 1/9 less"
maybe not correct words,
you can say F becomes 1/9th of its original value.

same for last.

all of your answers are correct :)

Answer 4

F is (1/9)th of the original,rest all are correct.

Answer 5

ohh, thank you very much :))
