When an ebonite rod rubbed with fur and a glass rod rubbed with silk are brought near each other, they exhibit a phenomenon known as electrostatic attraction. This is due to the transfer of electrons between the two objects during the rubbing process.

The rubbing of the ebonite rod with fur causes the fur to lose electrons and become positively charged. At the same time, the ebonite rod gains these electrons and becomes negatively charged. Similarly, when the glass rod is rubbed with silk, the silk loses electrons and becomes positively charged, while the glass rod gains electrons and becomes negatively charged.

Now, when the negatively charged ebonite rod is brought near the positively charged glass rod, they attract each other. This is because opposite charges attract each other according to the fundamental law of electrostatics. The negative charges on the ebonite rod are attracted to the positive charges on the glass rod, causing them to move closer to each other.

This electrostatic attraction between the two objects is a result of the electric field created by the charges on the rods. The electric field exerts a force on the charges, causing them to move in a certain direction. In this case, the charges on the ebonite rod and the glass rod experience a force that pulls them towards each other.

It is important to note that this attraction is temporary and only occurs when the charged objects are brought near each other. Once separated, the objects will retain their respective charges and can exhibit similar attractions or repulsions with other charged objects.

In conclusion, when an ebonite rod rubbed with fur and a glass rod rubbed with silk are brought near each other, they attract each other due to the electrostatic attraction between their opposite charges.
