Question

1. A person runs along a circular path of radius
5 m. If he completes half of the circle find the
magnitude of the displacement vector, How
far the person ran?
10 m, 51 m
2) 51 m, 10 m
3) 51 m, 19m 4) 14 m, 10 m​

Answer 1

ANSWER

Displacement is a vector from start to the final position. That is a straight line. It's same as the diameter of the circular path. Magnitude = 2*5= 10 m.
