Simple bet question ... was it enough?

Just moving up to 50NL ... villain was not really aggressive just playing the hands as they came. Overall the table was pretty passive. I called primarily because of boredom at the time (I normally would chuck this hand but ...).

Question: I bet 3/4 pot on the turn card now that I had 2 pair. Was that enough? I assumed villain had paired the K and nothing more.

Two low pair is very vulnerable, but the pot is only $2. 3/4 should be good, but since there are 4 in the pot, they can give each other odds to call. I usually bet just like you did here, but it might make sense to overbet the pot, since you almost definately have the best hand so far.

3/4-full pot is fine.

I bet $2 here just cause y0u only have to type one thing on the keyboard to do it
