A slab B rests on a frictionless floor as shown in the figure. A block A rests on top of the slab- B. The coefficients of static and kinetic friction between the block A and the slab B are and respectively. When block-A is acted upon by a horizontal force of , as shown, find the resulting acceleration of the slab- B. 
- A
- B
- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
The maximum frictional force, μsN=0.6×10×9.8=58 N As the frictional force is less than the applied force, the block and slab won't move together. For the block, f=μmg=0.4×10×0.98 ⇒f=39.2 N The slab moves due to the kinetic friction.…
