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 :
(Take acceleration due to gravity as 10 m/s2)
1
\(\frac{2+\sqrt{3}}{3}\)
2
\(\frac{2+\sqrt{2}}{3}\)
3
\(\frac{3+\sqrt{3}}{2}\)
4
\(\frac{3-\sqrt{2}}{2}\)
