Centre Of Mass Ques 19
- Distance of the centre of mass of a solid uniform cone from its vertex is $z _0$. If the radius of its base is $R$ and its height is $h$, then $z _0$ is equal to
(2015 Main)
(a) $\frac{3 h}{4}$
(b) $\frac{h^{2}}{4 R}$
(c) $\frac{5 h}{8}$
(d) $\frac{3 h^{2}}{8 R}$
Show Answer
Answer:
Correct Answer: 19.(a)
Solution:
Formula:
Mass Moment and Centre of Mass:
- Centre of mass of uniform solid cone of height $h$ is at a height of $\frac{h}{4}$ from base. Therefore from vertex it’s $\frac{3 h}{4}$.
