A spherical body of radius `R` rolls on a horizontal surface with linear velociltly `v`. Let `L_(1)` and `L_(2)` be the magnitudes of angular momenta of the body about centre of mass and point of contact `P`. Then: A. `L_(2)=2L_(1)`, if radius of gyration about centroidal axis K=RB. `L_(2)=2L_(1)`, for all casesC. `L_(2)lt2L_(1)`, if radius of gyration about centroidal axis `KltR`D. `L_(2)lt2L_(1)`, if radius of gyration about centroidal axis `KgtR` |
