An Atwood machine consists of two blocks (of masses m_1 and m_2) tied together with a massless rope that passes over a fixed, perfect (massless and frictionless) pulley.(adsbygoogle = window.adsbygoogle || []).push({});

For all parts of this problem, take upward to be the positive direction and take the gravitational constant, g, to be positive.

Now here's the problem: suppose m_1 goes to infinity while while m_2 remains finite. What value does the the magnitude of the tension approach??

I think it's m_2 times g, but I think that's not entirely correct. I tried to find the acceleration of m1 and concluded it was 0, and then thought that acceleration of m2 was g (positive, because it's going up) so that tension is just the sum of two forces... which is how i arrived at my partially correct answer m_2 times g.
