What is the magnitude of the displacement vector for each of the three girls who start skating from point P on a circular ice ground of radius 200 m and reach point Q, which is diametrically opposite to P, following different paths as shown in Fig. 3.19? For which girl is this magnitude equal to the actual length of the path skated?

Options

  1. AThe magnitude is the same for all three girls.
  2. BGirl 1 has the same magnitude as the actual length of the path skated.
  3. CGirl 2 has the same magnitude as the actual length of the path skated.
  4. DGirl 3 has the same magnitude as the actual length of the path skated.

Correct answer

C. Girl 2 has the same magnitude as the actual length of the path skated.

Step-by-step solution

Correct Option is : (C) Girl 2 has the same magnitude as the actual length of the path skated.
