A boy travels 8 km eastward to a point B and then 6km northward to another point C. Determine the difference between the magnitude of displacement of the boy and distance travelled by him

A. 2.0km
B. 4.0km
C. 10.0km
D. 13.0km

Correct Answer: Option B

B. 4.0km

Explanation

AC = √(8²+6²) = 10km

Distance travelled = 8 + 6 = 14km

Difference = i4 – 10 = 4km
