Explicación
## Step 1Triboelectric charging is a phenomenon that occurs when two different materials are rubbed together. This rubbing action causes a transfer of electrons from one material to the other, leading to an imbalance of charge. ## Step 2The material that loses electrons becomes positively charged, while the material that gains electrons becomes negatively charged. This is due to the fact that electrons carry a negative charge, and their transfer from one material to another results in an imbalance of charge.## Step 3The other options provided do not accurately describe triboelectric charging. Option B describes induction, which is the redistribution of charge in an object due to the presence of a charged object nearby, but without direct contact. Option C describes the effect of an external electric field on an object, which is not related to triboelectric charging. Option D describes the transfer of charge through a conducting wire, which is a process known as conduction, not triboelectric charging.
