thanks for the reply, I'm assuming that there is no friction. Could you tell me what went wrong with my "analysis"?

mg pulls on cord from the bottom, cord pulls on top mass by mg but by newton's third, it pulls back on the cord by mg? So the force applied to the top mass would've been mg but it's mg - mg because of the reaction force..?
