Due to polarization electrically neutral pieces of paper are attracted to a charged comb. true or...
Rub a comb through your hair and use it to lift pieces of paper. It may help to tear the pieces of paper rather than cut them neatly. Repeat the exercise in your bathroom after you have had a long shower and the air in the bathroom is moist. Is it easier to get electrostatic effects in dry or moist air? Why would torn paper be more attractive to the comb than cut paper? Explain your observations.
Object A is metallic and electrically neutral. It is charged by induction so that it acquires a charge of -2.82E-6 C. Object B is identical to object A and is also electrically neutral. It is charged by induction so that it acquires a charge of +2.82E-6 C. Calculate the difference in mass between the charged objects. Submit Answer Incorrect. Tries 2/10 Previous Tries
Honeybees actively foraging in the field have been found to be electrically charged, due largely to air resistance as they fly. The charges carried by a bee, which can be as great as 93 pC, is thought to play a significant role in pollination -- the bee can detach grains of pollen from a distance, like a charged comb attracting bits of paper. Given the force required to detach pollen from an avocado stigma is 4.5 ✕ 10-10 N, find...
Can an electrically charged object produce an electric force on a neutral object? Yes, if charge distribution in the neutral object is not uniform. This occurs often and naturally produces an attraction Yes, if charge distribution in the neutral object is not uniform. This occurs often and naturally produces a repulsion. No, never. Coulomb's Law clearly says the force must be zero. Yes, but only if the neutral object is moving.
help, please :) Which of the vectors correctly shows the polarization force on a neutral piece of metal due to the negatively charged rod? F, A) FA B) FB C) Fc E) 0
A long insulating rod suspended by insulating wires.Assume that the rod is initially electrically neutral. Forconvenience, we will refer to the left end of the rod as end A, andthe right end of the rod as end B . In the answer options for thisproblem, "weakly attracted/repelled" means "attracted/repelled witha force of magnitude similar to that which would exist between twoballs, one of which is charged, and the other acquires a smallinduced charge". An attractive/repulsive force greater than thisshould be...
An electrically neutral molecule is collinear with (and located between) two charged particles, one carrying a charge of +3.56 μC and the other carrying a charge of -1.05 μC. The center of the molecule is 2.57 μm from each particle. Part A If the vector sum of the electric forces exerted on the molecule is 45.0 nN , what is the polarizability of the molecule? Express your answer using two significant digits. α =
Object 1 is positively charged. Object 2 is neutral. Explain in detail WHY objects and 2 are attracted to each other by an electrostatic force. (I thought only oppositely charged objects are attracted to each other!) Use clear words and diagrams.

Charging by friction usually creates molecular ions as bonds are broken. E Like charges attract. An atom consists of a very small and dense nucleus surrounded by less massive orbiting electrons.

4. A p-type semiconductor has positive charge carriers but is electrically neutral. Similarly an n-type semiconductor has negative charge carriers but is electrically neutral. When they are put in contact (making a diode), statistical forces cause some of the charge carriers to migrate to the opposite semiconductor. The charge carriers move until an E-field is created to stop the migration. This E-field creates a depletion region near the junction where there are no charge carriers. If a forward voltage is...
