Question

A glass rod is rubbed with silk. It is found to attract a balloon. What

will be the charge on the balloon?​

Answer 1

By convention, we call one type of charge “positive”, and the other type “negative.” For example, when glass is rubbed with silk, the glass becomes positively charged and the silk negatively charged. ... A glass rod becomes positively charged when rubbed with silk, while the silk becomes negatively charged. A balloon has a negative charge. The glass rod has a positive charge. What will happen when the glass rod is brought near the balloon? ... the silk has become negatively charged
