Electrical Charge Distribution on a Metal Teapot

In summary: Your reasoning is thorough and correct. In summary, the correct answer is e) The teapot will remain neutral overall with negative charge on the side of the teapot closest to the rod and an equal amount of positive charge on the side of the teapot furthest from the rod.

Homework Statement



A positively charged glass rod is brought near to (but not touching) a neutral metal teapot. What will be the charge distribution on the teapot?

Homework Equations



None

The Attempt at a Solution


This is a multiple choice question, and the possible answers are:
-Excess negative charge will be created and it will be concentrated on the side of the teapot furthest from the rod.

a) Excess positive charge will be created and it will be concentrated on the side of the teapot closest to the rod.

b) Excess negative charge will be created and it will be concentrated on the side of the teapot closest to the rod.

c) The teapot will remain neutral overall with positive charge on the side of the teapot closest to the rod and an equal amount of negative charge on the side of the teapot furthest from the rod.

d) Excess positive charge will be created and it will be distributed evenly on the teapot.

e) The teapot will remain neutral overall with negative charge on the side of the teapot closest to the rod and an equal amount of positive charge on the side of the teapot furthest from the rod.

f) Excess positive charge will be created and it will be concentrated on the side of the teapot furthest from the rod.

g) Excess negative charge will be created and it will be distributed evenly on the teapot.

Would it be e, or "The teapot will remain neutral overall with negative charge on the side of the teapot closest to the rod and an equal amount of positive charge on the side of the teapot furthest from the rod." because it is an induced charge, first of all, and since electric charge cannot be created/destroyed, we can rule out a, b, d, f, and g. With only c and e left as answer choices, well since positive and negative charges attract, and the rod is positively charged, all the negative charge will gather towards the end closer to where the rod is.

Can someone check on this and tell me if it's right? Thanks!

I agree also.
 

Related to Electrical Charge Distribution on a Metal Teapot

1. What is electrical charge?

Electrical charge is a fundamental property of matter that causes it to experience an electric force when placed in an electric field. It can be either positive or negative and is measured in units of Coulombs (C).

2. How is electrical charge created?

Electrical charge can be created by the movement of electrons from one atom to another. This can occur through various processes such as friction, contact with other charged objects, or through chemical reactions.

3. What is the difference between static and current electricity?

Static electricity refers to the buildup of electric charge on the surface of an object, while current electricity refers to the flow of electric charge through a conductor. Static electricity is typically stationary and can cause small shocks, while current electricity is necessary for most electrical devices to function.

4. How is electrical charge measured?

Electrical charge is measured using a device called an electrometer, which uses a sensitive meter to measure the amount of charge on an object. Charge can also be measured indirectly by measuring the electric force between two charged objects.

5. What is the law of conservation of charge?

The law of conservation of charge states that electric charge cannot be created or destroyed, it can only be transferred from one object to another. This means that the total amount of charge in a closed system remains constant.
