Hollow spherical earthed conductor

In summary, three concentric hollow conducting shells with charges +q, -q, and 0 (earthed) are given. Using the equations v = kq/r and E = kq/r^2, and possibly Gauss's Law, one can find the charge appearing on all surfaces.

Hello @mit. Welcome to PF !

Use the X2 icon for superscripts, which gives E=k q /r2 .

Another relevant equation/formula is Gauss's Law: ##\displaystyle \ \oint \vec{E}\cdot d\vec{A}=\frac{q_\text{enclosed}}{\epsilon_0}\ . ##

According to the rules of this Forum, you need to show an honest attempt before we can help you.

That attempt can be in the form of showing what you know about aspects of the problem.
In this case, you may want to mention how Gauss's Law might help with this problem.​
 

1. What is a "hollow spherical earthed conductor"?

A hollow spherical earthed conductor is a type of electrical conductor that consists of a spherical shell made of a conducting material, such as copper or aluminum, that is connected to the ground or earth.

2. How does a hollow spherical earthed conductor work?

A hollow spherical earthed conductor works by providing a low resistance path for electrical currents to flow to the ground. This helps to protect electrical equipment and prevent electrical shocks to humans or animals.

3. What are the benefits of using a hollow spherical earthed conductor?

There are several benefits of using a hollow spherical earthed conductor, including providing protection against lightning strikes and power surges, reducing the risk of electrical fires, and ensuring the safe operation of electrical systems and equipment.

4. How is a hollow spherical earthed conductor installed?

A hollow spherical earthed conductor is typically installed by burying it in the ground or attaching it to a grounding rod or plate. It should be installed in a location where it can effectively divert electrical currents to the ground.

5. Are there any limitations to using a hollow spherical earthed conductor?

While a hollow spherical earthed conductor can provide effective protection against electrical hazards, it is not a foolproof solution. In some cases, such as with very high voltage systems or in areas with extremely dry soil, additional grounding measures may be necessary for optimal safety.
