**Problem text:**

Forces act on block A and block B, which are connected by a massless string. Force [itex]\vec{F}[/itex]

_{A}=(12 N)[itex]\hat{i}[/itex] acts on block A, with mass 4.0 kg. Force [itex]\vec{F}[/itex]

_{B}=(24 N)[itex]\hat{i}[/itex] acts on block B, with mass 6.0 kg. What is the tension in the string?

The system looks something like this:

[A]-----

F=ma

The professor never went over tension in class, so I've been Googling the pants off this problem and combing through the book for a solution, each to no avail. I tried working through it for about 30 minutes and gave up in frustration, after having come up with about 6 different answers.
