What is the gravitational field inside a hollow sphere?
The gravitational field inside a hollow sphere is zero. This is because the gravitational force from the spherical shell cancels out in all directions, resulting in no net gravitational force at the center or within the sphere.
What is the center of spherical mirror?
The geometric centre of a spherical mirror is called its pole. The centre of the hollow sphere for which the mirror is a part, is called the centre of curvature. The line joining the centre of curvature and the pole is the principal axis. A light ray incident on a spherical mirror, after reflection appears to pass through the principal focus in the case of a convex mirror and passes through the focus in the case of concave mirror. The diameter of the spherical mirror gives the measure of its aperture
How does the shell theorem affect the electric field inside a hollow spherical shell?
The shell theorem states that the electric field inside a hollow spherical shell is zero. This means that there is no electric field present within the shell, regardless of the charge distribution on the shell's surface.
Gravitation Force inside a sphere?
The gravitational force inside a solid sphere is zero because the gravitational forces from the parts of the sphere above cancel out the forces from the parts below, resulting in a net force of zero at any point inside the sphere. This is known as the shell theorem.
Why does gravity decreases with increase in depth?
The force of gravity inside a hollow shell is zero, according to an elegant theorem by Isaac Newton. Therefore at depth the force of gravity comes only from the sphere which has its radius equal to your distance from the centre.
The intensity of the gravitational field inside a hollow spherical shell is?
It is zero.

Can you prove the moon is hollow?
No. Gravitational and seismic analysis has already proven that the moon is not hollow.
What is the value of Earth's gravitational field at the center of the Earth?
In the cavity at the center of the Earth, your weight would be zero, because you would be pulled equally by gravity in all directions. - The gravitational field of Earth at its center is zero.
How do you sand cast hollow spherical shape?
You would have to make a core using a plaster based investment or a resin bound sand. The core would have to be supported in the centre of the sand mould by core pins which leave holes that have to be filled after the core material is removed.
How does the shell theorem affect the electric field inside a hollow spherical shell?
The shell theorem states that the electric field inside a hollow spherical shell is zero. This means that there is no electric field present within the shell, regardless of the charge distribution on the shell's surface.
What has the author Marie E Worley written?
Marie E. Worley has written: 'Wolf Hollow Wildlife Rehabilitation Centre' -- subject(s): Wildlife rehabilitation, Wolf Hollow Wildlife Rehabilitation Centre (Wash.)
Who said that the earth was a solid bodily freely hanging in the centre of the hollow heavens?
Aristotle
How do you define ball?
A ball is a spherical or approximately spherical body shape. It is also a round or roundish body, of various sizes and materials, either hollow or solid, for use in games, such as baseball, football, tennis, or golf.
What are the similarities and differences between concave and convex mirrors?
Definitions found on www.dictionary.com Concave: a curved like a segment of the interior of a circle or hollow sphere; hollow and curved Convex:having a surface that is curved or rounded outwardsBoth concave and convex mirrors are spherical mirrorsconcave mirrora spherical mirror whose reflecting surface is curved inwards is called a concave mirrorconvex mirrora spherical mirror whose reflecting surface is curved outwards is called a convex mirror
What are hollow tubes made of spherical protein subunits called tubulins?
Hollow tubes made of spherical protein subunits called tubulins are known as microtubules. These microtubules play a crucial role in cell structure, cell division, intracellular transport, and cellular movement in all eukaryotic cells. The dynamic assembly and disassembly of microtubules are tightly regulated in the cell.
