Answer» Correct Answer - A (a) If a particle is roting about on axis on its elf the orientain of the particle is not same under a different order of addition of angular displacement ,so it cannot be regarded as vector quantity . `d theta+d theta_(2)=d theta_(2)+d theta_(1)` `but theta_(1)+theta_(2) netheta_(2)+theta_(1)` |
