What is the induced charge on the inner surface of the spherical shell?

zero
Since the Electric field vanishes everywhere inside the volume of a good conductor, its value is zero everywhere on the Gaussian surface we have considered. So the surface integral is zero. This is the total charge induced on the inner surface.

What is the value of induced charge q in induction method?

q=(ϕ1​−ϕ2​)/NR.

What is the electric potential inside a spherical shell of charge Q and radius R?

A point charge q is placed inside a conducting spherical shell of inner radius 2R and outer radius 3R at a distance of R fro the centre of the shell. The electric potential at the centre of shell will (potential at infinity is zero).

What is the total charge on the inner surface of the outer sphere?

Since the total flux through the surface is zero, the total enclosed charge is zero and therefore the charge on the inner surface must be q (to cancel the charge −q in the center). Thus the total charge on the outer surface is Q−q.

What charge is enclosed by the shell?

0
The whole charge is distributed along the surface of the spherical shell. There’s no charge inside. Therefore, q-enclosed is 0. Since q-enclosed is 0, therefore we can say that the electric field inside of the spherical shell is 0.

What is the total charge on the inner surface of the small shell?

The total charge on the inner surface of the small shell is -2q.

What is induced charge?

In the induction process, a charged object is brought near but not touched to a neutral conducting object. When an object is charged by induction, the charge received by the object is opposite the charge of the object which was used to charge it.

What is induced charge in physics?

When a charged object is brought near an uncharged, electrically conducting object, such as a piece of metal, the force of the nearby charge due to Coulomb’s law causes a separation of these internal charges. These are called induced charges.

What is the electric potential of the spherical shell?

The potential is defined relative to the infinity – not relative to the center of the shell. Since there is no field inside the shell, the potential at any point inside the shell is equal to the potential on the surface of the shell, V=Q4πϵ0.
