Three spheres of different materials are in motion their radii, densities and speeds are as given
`{:("SI.NO","Radius","Density","Speed"),(1,r,d,v),(2,r//2,d,V//2),(3,2r,d//2,v):}`
If `K_(1),K_(2),K_(3)` are the kinetic energies of those three spheres respectively , those vlaues can be arranged in descending order as given below

Options

B. `K_(3),K_(1),K_(2)`
C. `K_(1),K_(2),K_(3)`
D. `K_(2),K_(1),K_(3)`

Answer

B
