Three girlsskatting on a circular ice ground ofradius200 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 Fig . 4.20 . Whatis the magnitude of the displacement vector for each ? for which girl is this equal to the actual length of path skate ?
