Dear student 
I assumed the mass is m/3 , an solved the question. 
the total mass of the system becomes m/3 + m = 4m/3
therefore acceleration  of the system = f/m=  3f/4m
let the length of the rope be l so,
for l mass is m/3 + m and for 
l/2 mass is m/6 + m    that bis 7m/6
 
therefor tension in the mid point =m *a
=7m/6*3f/4m
= 21f/24
