A solid sphere rolls down two different inclined planes of the same height but of different inclinationsA. the speeds will be same but time of descent will be differentB. . in both cases, the speeds and time of descent will be sameC. in both cases, the speeds and time of descent will be sameD. speeds and time of descent both will be different |

Answer» Correct Answer - A As ` sqrt((2gh)/(1+1/(MR^(2))))` Hence velocity is independent of te inclination of the plane and depend any on height `h` through which body descends. But because `t+1/(sintheta)sqrt((2h)/g(1+I/(MR^(2)))` depends on the inclination also, hence greater the inclination lesser will be the time of desced. Hence, in present cae the speeds will be same (became `h` is same) but time is decreased will be difference (because of different inclination) |
