Question

When an object rubbed with some materials, it acquires charges and becomes ______ object.

• A. uncharged
• B. charged
• C. neutral
• D. complex

Answer 1

The correct option is B charged

Charging by friction is the charging process which usually involves the rubbing together of two objects of dissimilar materials in order to transfer electrons from one object to the other. The object made of the material with the greatest affinity for electrons is the object which receives the electrons; the object with the lesser affinity for electrons provides the electrons. The process usually involves the rubbing of the two materials because it increases the amount of close intimate contact between the different atoms and allows for more electrons to be transferred.

Hence, it acquires charges and becomes charged object.
