उत्तर
An Ebonite rod is rubbed with fur.
Ebonite rod gains electrons and acquires negative charge while fur loses electrons and acquires positive charge.
Explanation
Suppose an ebonite rod has 7 protons and 7 electrons and fur has 10 electrons and 10 protons.
On rubbing together, fur loses 2 electrons and ebonite rod gains 2 electrons. Now fur has 8 electrons and 10 protons which makes it positively charged. The ebonite rod has 9 electrons and 7 protons making it negatively charged.
