Two blocks (A) and (B) of respective masses ma = 2 kg and mg = 3 kg, are placed in contact side by side on a horizontal smooth surface (friction is considered negligible). A pushing force of magnitude F = 20 N is applied on block A resulting in an acceleration of 4 m/s² . The magnitude of the force exerted by B on A is: O 10 N 20 N O 4 N 12 N
