See below.

Explanation:

For the object with mass 2M2M

T_1=2M a_1T1=2Ma1

For the pulley BB

T_1= 2T_2T1=2T2

For the object with mass MM

M g - T_2 = M a_2MgT2=Ma2

Kinematic constraint

a_2 = 2 a_1a2=2a1

Force actuating in pulley AA

F_c = sqrt 2 T_2Fc=2T2

Mounting now the system of equations

{(2 M a_1 = T_1), (T_1 = 2 T_2), (M g - T_2 = M a_2), (a_2 = 2 a_1), (F_c = sqrt[2] T_2):}

and solving we get

{(T_1 = (2 g M)/3), (T_2 = (g M)/3), (a_1 = g/3), (a_2 = (2 g)/3), (F_c = 1/3 sqrt[2] g M):}
