Find the acceleration acting on two objects if their masses are 5 kg and 10 kg respectively and they are separated by a distance of 12.5 m.

yeah you should definitely accelerate physics in year 11. itll definitely alleviate your workload in year 12!

lol wat

$Let m_{1} = 5\and\ m_{2} = 10$

$G=6.626\times\10^{-11}$

$r=12.5$

$F=G\frac{m_{1}m_{2}}{r^{2}}$

$F=6.626\times\10^{-11}\frac{5\times\10}{12.5^{2}}$

$F=2.1^{-11}N$

when i said "acceleration" i was referring to the acceleration of the objects in the question

Thanks heaps!

So do I just use F = ma for m1 and m2 to find the acceleration for each?

Um I think that is the answer? What does the answer say?
