I can't find what I'm doing wrong in this problem:(adsbygoogle = window.adsbygoogle || []).push({});

Equation: f= (Gm1m)/r^2

F1= (G*(8.5))/(.2)^2 = 1.417 x 10^-8

F2= (G*(12))/.5^2 = 3.2016x10^-9

Fnet= -1.417 x 10^-8 + 3.2016x10^-9 = -1.1x10^-8m

a= 1.1x10^-8, and this is wrong and I can't figure out where I messed up at.
