Which is an example of gaining a static charge by conduction?
c) bringing a charged rod near an electroscope
d) touching your car on a cold day and getting a shock
I knew that a and b were not the answer, but I couldn't figure out if it was c or d, so I only showed c and d.
To determine the answer, let's break down the options given:
c) bringing a charged rod near an electroscope
d) touching your car on a cold day and getting a shock
Conduction is the process of transferring charge through direct contact. In this case, we are looking for an example of gaining a static charge through conduction.
Option c) involves bringing a charged rod near an electroscope. Although this can demonstrate the effects of charge on the electroscope, it does not involve a direct contact, so it is not an example of conduction. Therefore, we can eliminate option c).
Option d) refers to the experience of getting a shock when touching your car on a cold day. This scenario involves direct contact between your body and the car's surface. As a result of this direct contact, charge can be transferred from the car to your body, resulting in a static charge. Therefore, option d) is an example of gaining a static charge by conduction.
So, the correct answer is:
d) touching your car on a cold day and getting a shock
By analyzing the options and understanding the concept of conduction, we determined that option d) is the correct answer.
