Two blocks are accelerated across a horizontal frictionless surface as shown. Frictional forces keep the two blocks from sliding relative to each other, and the two move with the same acceleration. If F = 1.2 N and M = 1.0 kg, what is the horizontal component (frictional force) of the force of the small block on the large block?
A)0.48 N to the right
B)0.72 N to the right
C)0.72 N to the left
D)0.48 N to the left
E)0.65 N to the left
