Laws of motions question

None

Okay for this question I got the correct angle 37 degree and I even got the acceleration as 7.5 m/s^2. But, I am not able to get the correct value of F. How do I calculate it correctly, please help ?

As the total mass of system is 3*7+2= 23 kg so F should be 7.5*23So right answer is (d) None of these(Taking your words, I am assuming that a=7.5 and theta = 37 is correct)
