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 is 10 m/s. The ratio of its kinetic energies at point and is :

(Take acceleration due to gravity as $$10 m/s^{2}$$)

A

$$\frac{2+\sqrt{2}}{3}$$

B

$$\frac{2+\sqrt{3}}{3}$$

C

$$\frac{3+\sqrt{3}}{2}$$

D

$$\frac{3-\sqrt{2}}{2}$$
