Two blocks, \( 4 \mathrm{~kg} \) and \( 2 \mathrm{~kg} \) are sliding down an incline plane as shown in figure. The acceleration of \( 2 \mathrm{~kg} \) block is
[Odisha JEE 2008]
(a) \( 1.66 \mathrm{~m} / \mathrm{s}^{2} \)
(b) \( 2.66 \mathrm{~m} / \mathrm{s}^{2} \)
(c) \( 3.66 \mathrm{~m} / \mathrm{s}^{2} \)
(d) \( 4.66 \mathrm{~m} / \mathrm{s}^{2} \)
