Problem

Three displacement vectors lie along the same straight path: P is 6 cm long pointing right, Q is 4 cm long pointing left, and R is 3 cm long pointing right. With the scale 1 cm → 2 m, which single arrow best represents the resultant displacement? (a) A 7 cm7\text{ cm} arrow pointing right (+14 m)(+14\text{ m}) (b) A 1 cm1\text{ cm} arrow pointing left (−2 m)(-2\text{ m}) (c) A 5 cm5\text{ cm} arrow pointing right (+10 m)(+10\text{ m}) (d) A 5 cm5\text{ cm} arrow pointing right (+5 m)(+5\text{ m})
