Okay so I ran into this question while solving problems from my physics textbook and I need some help to understand the concept involved in it.
Question: In the shown arrangement if $f_1$, $f_2$ and $T$ be the frictional forces on $2$ kg block, $3$ kg block & tension in the string respectively , then what are their values?
Doubt: But what I don't get is that how should I determine the direction of friction on the two blocks? Also, how do I figure out if the system is at rest or is it moving with some acceleration? The answer is certainly coming different in the two cases. Another doubt that I have is how do I know if there is maximum value of friction acting on the blocks or not and how do I determine that?
Please let me know how you would go about solving similar problems and what's the idea behind this friction thing.
