Question

A charged glass rod attracts a charged plastic straw.

• A. True
• B. False

Answer 1

The correct option is A True

1. A charged plastic straw has a negative charge on its surface while a glass rod has a positive charge on its surface.
2. Because When a plastic straw is rubbed with say polythene, plastic becomes negatively charged due to excess electrons.
3. Similarly, When a glass rod is rubbed with say polythene, the glass rod becomes positively charged due to a lack of electrons.
4. Unlike charges attract each other, so a positively charged glass rod attracts a negatively charged plastic straw

Hence, the given statement is true.
