Two blocks on a frictionless horizontal surface are connected together by a massless string. A second massless string is attached to the block of mass m2, as shown. Suppose you pull on this second string with a horizontal force directed to the right.

Determine the ratio of the tensions for the two strings.

NOTE: THE PICTURE SHOWS ONE BLOCK LARGER THAN THE OTHER. HOWEVER, IN THIS QUESTION WE ACTUALLY DO NOT KNOW WHICH BLOCK IS LARGER.

2. Relevant equations

Let T= tension

use ratio: T1/T2

3. The attempt at a solution

So, would it just simply be (T(m2onm1))/(T(Fonm2) - T(m1onm2))

where m2onm1 is the subscript of the 1st T, Fonm2 is the subscript of the 2nd T, and m1onm2 is the subscript on the 3rd T.

(These are the action reaction forces I obtained by completing a free body diagram- Tm2onm1 with Tm1onm2. The T(Fonm2) is the force the second string applies on block m2).

Or is the question asking more than that? Are they asking, what does T1/T2 equal ? I am not sure if I understood the question correctly..

Please help!

Thank-you!
