Show answer
2 N to the right N (±0)
Must show: Correct subtraction, States direction
Also accept: Resultant force is 2 N rightwards; 2 N right
Common mistakes: Addition instead of subtraction; States 2 N but no direction

Marking points
M1 · 1 mark · Subtracts the forces (7 N - 5 N) correctly.
A1 · 1 mark · Gives the correct size (2 N) and direction ('to the right').
Worked solution
Resultant force = 7 N (right) – 5 N (left) = 2 N to the right.
