Two forces, 10 N forward and 6 N backward, act on a block. The net force is:

A16 N forward, the sum of magnitudes
B4 N forward, the difference, with the larger force's direction
C6 N backward, equal to the smaller of the two forces
D0 N because the two forces cancel out
Answer & Solution
Correct answer: B. 4 N forward, the difference, with the larger force's direction
Opposite forces give net = difference in magnitudes, in the direction of the larger force. Net = 10 - 6 = 4 N forward.
