When an object gets negatively charged by the process of friction, then C. the object gains some electrons.
Explanation:
- A matter is charged by three process such as charging by induction, charging by contact and charging by friction.
- Charging is defined as loss or gain of electrons.
- When a glass rod and silk cloth is rubbed with each other. Silk cloth becomes negatively charged and glass rod becomes positively charged.
- Silk cloth gains electrons from glass rod whereas glass rod losses electrons to silk cloth.
- Here, the charging takes place by friction.
