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
2.0km
4.0km
10.0km
13.0km
Correct answer is B
AC = \(\sqrt{8^2 + 6^2}\) = 10km
Distance travelled = 8 + 6 = 14km
Difference = 4 - 10 = 4km
