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 the fig. What is the magnitude of the displacement vector for each? For which girl is this equal to the actual length of path skated?

Best answer

Displacement of each girl = vector PQ = magnitude of the displacement for each girl.

= PQ = diameter of the circle (ice ground) = 2 x 200 = 400 m.

Actual path length in case of girl B is the least, i.e., equal to the displacement vector. For girls A and C it is the actual length of the path, so it is not equal to the diameter but is grater than that.
