A student in your class is confused about the balloon sticking to the wall. She makes the following statement:

We studied Coulomb’s Law in class. Coulomb’s Law states that the electric force between two charged objects is proportional to the product of their charges (F ~ q₁q₂). I know the balloon is charged, it’s clear that there is a net charge if I toggle “show charge differences” in the simulation. However, the wall shows no charge difference, it’s still neutral, which means its charge is zero. Anything times zero is zero, so how can there be a force between the wall and the balloon?

Can you help your classmate explain this challenging problem?

Expert Solution

Theory : Dipole moment : On presence of external Field the neutral atoms of the wall get polarised with one type of charges facing ballon and the other type facing away

Solution:

The approach to solve such questions is to go step by step

The ballon is charged baloon as stated,.

The charged ballon definitely has some electric field

The ballon when goes near the wall , induces dipoles in the wall.

I.e let's say the ballon is positively charged , this charged tries to exert force on neutral atoms on the wall,

The neutral atoms of wall form dipoles and negative part of atom faces the ballon and positive part faces away from ballon ,

The neraby positive and negative parts of atoms in the wall sum to zero, but the egdes have induced charges because of charge of ballon , and hence have net electric field and attract the ballon to it.

The best life example is from chapter Magnetism:

Normally Iron doesn't attract anything towards it , but why does it attract a magnet, beacuse on bringing magnet towards it , magnetic dipole field induces in the iron

Consider a student who is rather irregular about class attendance. If she attends class one day, the probability is .8 that she will attend class the next day. And if she misses class, the probability is .4 that she will miss again the following day. a. Set up the transition matrix for this stochastic process. b. If the student attends the first day of class, what is the probability she will miss the third day of class? c. In the...

A first-year accounting student is confused by a statement made in a recent class. The instructor stated that assets listened in the balance sheet of IBM Corporation include computers that are classified as current assets as well as computers that classified as long-term (noncurrent) assets. In addition, the instructor stated that investments in equity securities of other corporations could be classified in the balance sheet as either current or long-term assets. Explain to the student the distinction between current and...

Your grandmother has turned 65 and is very confused about Medicare. She does not understand why there are four parts to this healthcare program. She has asked you to help her with enrolling in Medicare. How will she enroll in Medicare? List the different parts of Medicare and explain what each part is and why it may be important to your grandmother. Your grandmother has no previous experience in Medical Terminology so you must explain in layman's terms.

A student with an eight o'clock class at a university commutes to school by car. She has discovered that along each of two possible routes her traveling time to school (including the time to get to class) is approximately a normal random variable. If she uses the highway for most of her trip,μ=22 minutes and σ=5 minutes. If she drives a longer route over city streets, μ=26 minutes and σ=33 minutes. Which route should the student take if she leaves...
