Problem

A body of mass 100 g is moving in circular path of radius 2 m on vertical plane as shown in figure. The velocity of the body at point A is 10 m/s. The ratio of its kinetic energies at point B and C is : [Jan. 22, 2025 (II)] ![Diagram showing a vertical circle of radius R. O is the center. A is the lowest point, D is the highest point. C is on the right side, and B is on the right side, below C. The angle between the vertical line OD and the line OC is 90 degrees. The angle between the vertical line OD and the line OB is 30 degrees.](https://storage.googleapis.com/diraq-contents/homework-question-parsing/marker/20260106T182719Z/06492ae5a0e7442bb55e32532655ece4/935eed7aa61f7777f62cfc032e11bee9_img.jpg)
