Understanding Electrostatics: Exploring Charge Induction in a Hollow Sphere

In summary, a teacher explained that if a hollow sphere made of conducting material has a positive charge placed inside, a negative charge will be induced on the inner surface. This, in turn, causes the outer surface to become positively charged. This occurs because the positive charge on the inside attracts electrons, resulting in a negative charge on the inner surface and a positive charge on the outer surface. This is due to the conservation of charge in the conductor.

Some teacher told me this If we have hollow sphere (of conducting material) with some thickness. and if we place a +ve charge inside that . -ve charge induces on inner surfuce, Which further causes in outer sphere & that becomes positivly charged. is this right? Please give right explanation.

Yeah. Thats right. The positive charge on the inside attracts the electrons present inside the sphere, which causes the inner surface to be negatively charged. Since charge must be conserved, the positive charge centers in the conductor are pushed to the surface. Hence the inner surface is negatively charged and the outside surface is positively charged.

Yes, this is a correct explanation of charge induction in a hollow sphere. When a positive charge is placed inside the hollow sphere, the negatively charged electrons within the conducting material will be repelled and move to the inner surface of the sphere. This creates a negative charge on the inner surface of the sphere. The negative charge on the inner surface will then repel the electrons on the outer surface of the sphere, causing them to move away and leaving a positive charge on the outer surface. This process is known as charge induction. It is important to note that the thickness of the conducting material does not affect the process of charge induction, as long as the material is able to conduct electricity. This phenomenon is a fundamental concept in electrostatics and has many practical applications, such as in capacitors and electrostatic shielding.
 

FAQ: Understanding Electrostatics: Exploring Charge Induction in a Hollow Sphere

What is an electrostatic problem?

An electrostatic problem is a situation where there are stationary electric charges present, causing interactions and forces between them. These interactions can be described using the principles of electrostatics.

What are some examples of simple electrostatic problems?

Some examples of simple electrostatic problems include a charged object interacting with a neutral object, two charged objects interacting with each other, and the behavior of charges on conductors.

How do you calculate the electric force between two charges?

The electric force between two charges can be calculated using Coulomb's Law, which states that the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

Can electrostatic problems be solved using vector quantities?

Yes, electrostatic problems can be solved using vector quantities. Electric fields and forces are vector quantities, meaning they have both magnitude and direction. This is important when considering the direction of the force between two charges.

What is the difference between an electric field and an electric potential?

An electric field is a vector quantity that describes the force experienced by a charge at a given point. Electric potential, on the other hand, is a scalar quantity that describes the potential energy of a charge at a given point. Electric potential is related to the electric field by the equation V = Ed, where V is the potential, E is the electric field, and d is the distance.
