Write the law of conservation of charge. Give one example.
Discuss the phenomena experienced due to electrostatics.
If $10^{9}$ electrons move out of a body to another body every second. how much time is required to get a total charge of $1 \,C$ on the other body?
What is called polarity of electric charge ?
Sure check for presence of electric charge is
