In the given figure the coefficient of friction between \( 4 \mathrm{~kg} \) and \( 5 \mathrm{~kg} \) blocks is 0.2 and between \( 5 \mathrm{~kg} \) block and ground is 0.1 respectively. Choose the correct statements
(a) Minimum force needed to cause system to move is \( 17 \mathrm{~N} \)
(b) When force is \( 4 \mathrm{~N} \) static friction at all surfaces is \( 4 \mathrm{~N} \) to keep system at rest
(c) Maximum acceleration of \( 4 \mathrm{~kg} \) block is \( 2 \mathrm{~m} / \mathrm{s}^{2} \)
(d) Slipping between \( 4 \mathrm{~kg} \) and \( 5 \mathrm{~kg} \) blocks start when \( F \) is \( 17 \mathrm{~N} \)
