What is spherical shell?

In geometry, a spherical shell is a generalization of an annulus to three dimensions. It is the region of a ball between two concentric spheres of differing radii.

Is spherical shell same as hollow sphere?

Spherical shell means it is hollow inside. If shell and sphere are made of metal then there is no diffrence.

Is spherical shell a solid sphere?

We have to remember that the mass, value of g and r in both the cases i.e., solid sphere and spherical shell are the same as both are of the same mass and radius. The value of S is also the same as both are rolling down the same length of inclination.

How can you tell the difference between a hollow sphere and a solid sphere?

Since the moment of inertia of a hollow sphere is more than the moment of inertia of a solid sphere, hence we can say that the acceleration is greater for solid sphere than the hollow sphere. So the solid sphere reaches the bottom with greater speed. Hence the correct answer is option B.

What is the name of a hollow sphere?

A zygote initially develops into a hollow sphere, called a blastula, which undergoes rearrangement and differentiation.

Is hollow conducting sphere?

A hollow uncharged spherical conducting shell has an inner radius a and an outer radius b. A positive point charge q is in the cavity at the center of the sphere. The field due to a spherically symmetric charge distribution can be found from Gauss’ law. The inside of a conductor is field free in electrostatics.

What is a hollow sphere called?

How do you find the shell of a sphere?

Spherical shell: Outer surface area spherical shell=4πR2. Volume of material used for spherical shell=43π(R3−r3)

Is a ping pong ball hollow or solid?

Both ball types are hollow and have the same diameter but deform in very different ways. Ping pong balls are relatively stiff and buckle inwards at high impact speeds, while squash balls are softer and tend to squash or flatten.

Which rolls faster a hollow or solid sphere?

You should find that a solid object will always roll down the ramp faster than a hollow object of the same shape (sphere or cylinder)—regardless of their exact mass or diameter.

What is thin sphere?

A spherical shell will be considered as thin spherical shell, if the wall thickness of shell is very small as compared to the internal diameter of the shell. Wall thickness of a thin spherical shell will be equal or less than the 1/20 of the internal diameter of shell.

What is the difference between a shell and a sphere?

Spherical shell means it is hollow inside. If shell and sphere are made of metal then there is no diffrence. If they are made of non-metal and charge homogeneous ly distributed then also they can be treated equally but if non homogeneous than not equal.

What is the electric field of a spherical shell?

If the spherical shell and sphere are made of metal then there is no diffrence as all charge will reside on the surface in both cases. But if the sphere is non metallic then charge residing inside layers of sphere can not come out to surface. Electric Field is inversely proportional to the distance from charge.

What is the density of charge on a spherical shell?

Spherical shell means it is hollow inside. If shell and sphere are made of metal then there is no diffrence. If they are made of non-metal and charge homogeneous ly distributed then also they can be treated equally but if non homogeneous than not equal. Density of charge = total charge / area or volume.

Is charge homogeneously distributed in sphere or non homogeneous?

Now two cases arises. Is charge homogeneously distributed in sphere or non homogeneous. If it homogeneous then it can be treated as point charge which is equivalent to spherical shell (Only in situations where sphere is considered in its entirety). If it is non homogenous then spherical shell and sphere are not same.
