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
Verified Correct Answer: B.
Physical Principles & Numerical Solution
AC = \(\sqrt{8^2 + 6^2}\) = 10km
Distance travelled = 8 + 6 = 14km
Difference = 4 - 10 = 4km
