A piece of woll is rubbed against a PVC...

A piece of woll is rubbed against a PVC strip. What will be the charge on the strip, if approximately `2xx10^12` electrons are transferred from the wool to the PVC strip ?

Text Solution

AI Generated Solution

To determine the charge on the PVC strip after rubbing it with wool, we can follow these steps: ### Step 1: Understand the transfer of electrons When wool is rubbed against a PVC strip, electrons are transferred from the wool to the PVC strip. This means that the PVC strip gains electrons and becomes negatively charged, while the wool loses electrons and becomes positively charged. ### Step 2: Identify the number of electrons transferred According to the problem, approximately \( n = 2 \times 10^{12} \) electrons are transferred from the wool to the PVC strip. ...
