Conservation of charges in tribo electric charginga)implies both are n...
Explanation:The triboelectric effect (also known as triboelectric charging) is a type of contact electrification in which certain materials become electrically charged after they come into frictional contact with a different material. Rubbing glass with fur, or a plastic comb through the hair, can build up triboelectricity.When we charge something with static electricity, no electrons are made or destroyed. No new protons appear or disappear. Electrons are just moved from one place to another. The net, or total, electric charge stays the same. This is called the principle of conservation of charge.If a glass rod is rubbed with silk, some electrons moves from glass rod to silk no new charge is generated or destroyed.

Conservation of charges in tribo electric charginga)implies both are n...
**Explanation:**
In triboelectric charging, objects become charged through friction when two different materials come into contact and then separate. The process involves the transfer of electrons between the two materials, resulting in one material becoming positively charged and the other becoming negatively charged.
The conservation of charges states that charges cannot be created or destroyed; they can only be transferred from one object to another. This means that the total charge before and after the triboelectric charging process must be the same.
When two materials are rubbed together, the process can lead to the transfer of electrons from one material to the other. The material that gains electrons becomes negatively charged, while the material that loses electrons becomes positively charged. This transfer of electrons is what causes the objects to become charged.
Now, let's consider the possible options:
a) Implies both are negatively charged: This option is incorrect because the conservation of charges tells us that the total charge must remain the same. If both objects were negatively charged, there would be an overall excess of negative charge, which violates the conservation of charges.
b) Implies half are positively charged and the other half are neutral: This option is also incorrect. The triboelectric charging process involves the transfer of electrons, so there cannot be a situation where half of the objects are neutral. The conservation of charges requires that the total charge remains the same.
c) Implies one is positively charged and the other is negatively charged: This option is correct. As explained earlier, when two materials are rubbed together, electrons are transferred from one material to the other. This transfer of electrons results in one material becoming positively charged and the other becoming negatively charged. The conservation of charges is satisfied because the total charge remains the same.
d) Implies both are positively charged: This option is incorrect because the triboelectric charging process involves the transfer of electrons, resulting in one material becoming positively charged and the other becoming negatively charged. If both materials were positively charged, there would be an overall excess of positive charge, which violates the conservation of charges.
In conclusion, the correct answer is option 'C', which states that in triboelectric charging, one material becomes positively charged and the other becomes negatively charged. This is consistent with the conservation of charges.
