A 10 N force is applied on B. All surfaces are smooth. Mass of A & B are 5 kg each. What is the acceleration of A (in m/s²)?

Answer
0 m/s²
Explanation
Solution
Due to the smooth surface between blocks A and B, there is no horizontal friction force acting on block A from block B. Since there are no other horizontal forces acting on block A, the net horizontal force on A is zero. By Newton's second law, the acceleration of A in the horizontal direction is zero.
