Question
When a plastic rod is rubbed with a wool cloth, the wool acquires a positive charge. What is the best explanation for this effect?A protons are transferred to the clothB protons are transferred to the rodC electrons are transferred to the clothD electrons are transferred to the rod
Solution
The best explanation for this effect is D: electrons are transferred to the rod.
Here's the step by step explanation:
-
When a plastic rod is rubbed with a wool cloth, friction is created.
-
This friction causes a transfer of electrons from one object to another.
-
In this case, the wool cloth loses electrons to the plastic rod.
-
As a result, the wool cloth becomes positively charged (since it has lost negatively charged electrons), and the plastic rod becomes negatively charged (since it has gained negatively charged electrons).
So, the correct answer is D: electrons are transferred to the rod.
