A block of mass 50 kg is lying on a rough surface having coefficient of static friction 0.6 and that of dynamic friction 0.4. A force just sufficient to start the motion of the block acts on it and continues to act even after the block comes into motion. The acceleration of the block is
\(\text { (Take } \left.g=10 \mathrm{~m} / \mathrm{s}^{2}\right)\)
- Zero
- \(2 \mathrm{~m} / \mathrm{s}^{2}\)
- \(3 \mathrm{~m} / \mathrm{s}^{2}\)
- \(6 \mathrm{~m} / \mathrm{s}^{2}\)
Answer
(B) 2 ~m / s ^ 2
