Two small rings each of mass 'm' are connected to the block of same mass 'm' through inextensible massless string of length l. Rings are constrained to move along smooth rod AB. Initially system is held at rest as shown in figure. Let u and v be velocities of ring and block respectively when strings make an angle 60 0 with vertical. (Take g = 10 m/s 2 )

u = 
B
u = 
C
v = 
D
