Question

Block A of mass 4 kg and block B of mass 6 kg are resting on a horizontal surface as shown in the figure. There is no friction between the block B and the horizontal surface. The coefficient of friction between the blocks is 0.2. If the value of g=10 m/s2, the maximum horizontal force F that can be applied on block B without any relative motion between A and B is (A) 20 N (B) 40 N (C) 60 N (D) 100 N

We know that F=ma For combination of blocks m=10 kg and a=2 m/s2 F=10× 2 F=20 N

20 N

40 N

60 N

100 N

We know that F=ma For combination of blocks m=10kg and a=2m/s2 F=10×2 F=20N

We know that $F = ma$ For combination of blocks $m = 10 k g$ and $a = 2 m / s^{2}$ $F = 10 \times 2$ $F = 20 N$
