For the arrangement shown in figure the coefficient of friction between the two blocks is \( \alpha \). If both the blocks are identical are identical and moving, then the acceleration of each block is
Smooth
(a) \( \frac{F}{2 m}-2 \alpha g \)
(b) \( \frac{F}{2 m} \)
(c) \( \frac{F}{2 m}-\alpha g \)
(d) Zero
