I'm studying physics but in this question I can't figure out the free body diagram.

For $m\_3$:

$$T-m\_3 g = m\_3a
$$

For $m\_2$ along the y-axis:

$$N - (m\_2 + m\_1)g = 0
$$

But I can't figure out the x-axis forces on $m\_2$. 

Sorry about this basic question. I have no choice to ask anybody else.

Edit:

Now, I'm trying to find T equation on $m\_3$

@Steeven said $$T = m\_2a$$ so when I try to solve it $a=20m/s^2$

It is seems not right. 

Final:

At the top first equation should be like this.
$$m\_3g - T = m\_3a
$$
After that it seems correct.
