Four girls skating on circular ice groun...

Four girls skating on circular ice ground of radius 200 m start from a point P on the edge of the ground and reach a point Q diametrically opposite to P following different paths as shown in figure. For which girls displacement is equal to the actual length of path ?

A

A

B

B

C

C

D

D

Text Solution

Verified by Experts

The correct Answer is:
C
Displacement of each girl `= vec(PQ)`
Magnitude of displacement for each girl
` = |vec(PQ)| = 2 xx 200` m = 400 m
For girl C, displacement = actual length of path.
