Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

When a charged object contacts another object (one is usually a conductor), there is a transfer of electrons. How do you determine which object acquires the transferred electrons?

A	Always transfer from the bigger to the smaller object, to make it even
B	Transfer is based on the initial charge of the two objects
C	Transfer is based on how much electron affinity that each object has
D	Always transfer from the more negative to the more positive object

Explanation:

Detailed explanation-1: -a. During charging by friction, electrons are transferred from one object to the other object. The object which acquires a + charge is the object which loses the electrons.

Detailed explanation-2: -Conduction occurs when there is direct contact between materials that differ in their ability to give up or accept electrons. Polarization occurs whenever electrons within a neutral object move because of the electric field of a nearby charged object.

Detailed explanation-3: -Electrical charge can be transferred from one object to another object through conductors. because conductors have free electrons that carry charges from one object to another object.

Detailed explanation-4: -When two different materials are rubbed together, there is a transfer of electrons from one material to the other material. This causes one object to become positively charged (the electron loser) and the other object to become negatively charged (the electron gainer).
