True / False

When a polythene piece is rubbed with wool, it acquires negative charge.

Solution

When a polythene piece is rubbed with wool, both gets electrified due to charging by friction. Since polythene has greater electron affinity (ability to attract electrons) as compared to wool. So, polythene piece attracts electron and acquires negative charge and wool acquires positive charge.
