Question

Assume that the Styrofoam slab and the fur are both initially neutral, and that the slab charged negatively after it is rubbed with the fur. Describe what happens. Mark all the correct statements among those provided below. Mark all the correct statements among those provided below.
1. Protons move from the fur to the slab.
2. Protons move from the slab to the fur.
3. Electrons move from the fur to the slab.
4. Electrons move from the slab to the fur.
5. The fur becomes negative after rubbing the slab.
6. The fur becomes positive after rubbing the slab.
7. The fur remains neutral after rubbing the slab.

Answer 1

Charging phenomenon is basically transfer of electrons from one system to other. When a system loses the electrons the it becomes positively charged and when a system gains electrons then it will become negatively charged

so here if slab is rub against fur then one of them will lose the electrons while other will gain the electrons and hence one will get negatively charged and other will get positive charge

Here it is given that slab get negatively charged so correct options are

3. Electrons move from the fur to the slab.

6. The fur becomes positive after rubbing the slab.

Answer 2

The statements 3 and 6 are correct, because as slab is rubbed against fur, then it will acquire negative charge due to electron gains. And consequently, fur will acquire the positive charge.

According to the concept of static discharge, the species which losses electrons, acquire positive charge and species which gains electrons, acquire the negative charge.

1. As per the statement, "Protons move from the fur to the slab", there is transfer of protons. Since, static discharge occurs due to transfer of electrons. So, the statement is incorrect.
2. "Protons move from the slab to the fur", this is also the case of proton transfer for which static discharge is not possible. Hence, statement is incorrect.
3. "Electrons move from the fur to the slab", in this case slab will acquire negative charge and fur will be positive. Hence, this statement is correct.
4. "Electrons move from the slab to the fur", in this case the reverse will occur, that is fur will gain negative charge and slab will acquire positive charge. So, the statement is incorrect.
5. "The fur becomes negative after rubbing the slab", this does not match the given condition hence the statement is incorrect.
6. "The fur becomes positive after rubbing the slab". The fur will acquire positive charge due to loosing of electrons. Hence, the statement is correct.
7. "The fur remains neutral after rubbing the slab". Loosing electrons cause positive polarity. So, the statement is incorrect.

Thus, we conclude that statements 3 and 6 are correct, because as slab is rubbed against fur, then it will acquire negative charge due to electron gains. And consequently, fur will acquire the positive charge.
