Take an elemental mass on the solid hemisphere. Let the mass be in thin form of discs. The centre of mass lies at the centre of the disc. Integrate the whole function to get the c.o.m.

Is center of gravity lies where there is no mass?

That all depends on the shape of the object and how its mass is distributed. The center of gravity of a solid sphere is at the center of the solid sphere. The center of gravity of a solid cube is at the center of the solid cube. The Earth's center of gravity is at the center of the Earth, and there's certainly plenty of mass there. But the center of gravity of a ring is at the center of the ring ... an open space where the finger goes.


How do you find the center of mass of the raindrop?

To find the center of mass of a raindrop, you can calculate it by considering the raindrop as a uniform solid object. For a symmetric raindrop shape, the center of mass will lie at the geometric center. For irregular shapes, you can divide the raindrop into smaller parts, calculate the center of mass for each part, and then find the overall center of mass using these individual centers.


What is the Moment of inertia of a solid hemisphere?

The moment of inertia of a solid hemisphere rotating around its axis is given by (2/5) * m * r^2, where m is the mass of the hemisphere and r is the radius.


How do find mass of a regular solid?

Use a digital mass scale or a triple-beam-balance scale to find the mass of a regular solid.


What is the center of mass of a solid cylinder?

The center of mass of a solid cylinder is at its geometric center, which is the midpoint of its axis. This point represents the balance point of the cylinder, where its mass is evenly distributed in all directions.


Does the center of mass of a solid subject necessirly lie within the objects if not give examples?

No, the center of mass of a solid object does not necessarily have to lie within the object. For example, a hollow sphere or a ring has its center of mass located outside of its physical structure. This is because the distribution of mass in these objects is not uniform.


What instrument is used to find the mass of a solid?

A balance or scale is typically used to find the mass of a solid. The solid is placed on the balance, and its mass is measured in units such as grams or kilograms.


Two unequal masses are attached to the ends of a solid rod. which mass is nearest to the Centre of Mass lighter or heavier?

The heavier mass will be nearest to the center of mass. The concept behind this is related to the one that explains the center of gravity. The center of mass and the center of gravity are the same.


How do you find the center of rotation?

you can find center of earth by using only the formulas


What continent is at the center of the northern hemisphere?

The centre of the Northern Hemisphere is the northern rotational pole of the planet. This is situated in the Arctic Ocean, not a land/continental mass.


Where is the earths gravity concentrated?

Every speck of mass throughout any solid body "has gravity", and attracts every other speck of mass. But when you're outside of the solid body, the gravitational effect of all those specks of mass is exactly as if all of its mass were located at its "center of mass" or "center of gravity". For a homogeneous spherical object, that point is the center of the sphere.
