If m1=2m2, and the same force F is applied on these two objects, what would the ratio of acceleration a1/a2 be? Me attempt: F=m1a=F=2m2a F=m2a 2(m2)a1=m2a2 a1/a2=m2/2m2 Thank you very much

Almost right, you simply didn't finish it. You can cancel the common m2 on the right hand side of the last equation to get a1/a2 = 1/2.
