Question

A glass rod is suspended from a string and charged by rubbing it with a piece of silk.A. After rubbing, what type of charge will be on each object?B. What will happen if the silk is brought close to the glass rod?

Answer 1

A. Glass rod: Positive

Silk: Negative

B. They will attract each other

Step-by-step explanation:

A silk has a stronger tendency to gain electrons than the glass rod. So, after rubbing, the silk will gain electrons and it will become negatively charged ans the glass rod will lose electrons and it will becamo positively charged.

Then, the glass rod and the silk will have opposite charges, so when the silk is brought close to the glass rod, they will attract each other.
