Question

Three girls skating on a 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. What is the magnitude of the

displacement for each ? For
which girl is this equal to the actual length of path skate?​

Answer 1

Answer:

since the radius is 200 m

and girl start from point p and reach q I.e opposite to the point that's why

displacement is 400, and distance will be calculated by "pi R"
