A solid hemisphere and a solid cone have a common base and are made of same material. The centre of mass of the common structure coincides with the centre of the common base. If R is the radius of hemisphere and h is height of the cone, then A. `(h)/(R )=sqrt(3)`B. `(h)/(R )=(1)/sqrt(3)`C. `(h)/(R )=3`D. `(h)/(R )=(1)/(3)` |

Answer» Correct Answer - C We have `(1)/(2)Mv^(2)=(1)/(2)kl^(2)` `v=sqrt((k)/(M))l` Maximum momentum `=Mv=Msqrt((k)/(M))l=sqrt(Mk)l` |
