When any atom donates the electrons the atoms acquires positive charges on it. As the glass rod is rubbed on the silk cloth the glass emits out electrons and acquire positive charges. The electrons are accepted by the silk cloth and then acquire negative charge.. This builts up the electromagnetic force of attraction between the glass rod and the silk cloth....

Explanation:
When a glass rod is rubbed with silk, it becomes positively charged. This is because electrons are transferred from the glass rod to the silk.
Electrostatics:
Electrostatics is the study of electric charges at rest. It deals with the behavior of stationary or slow-moving electric charges.
Charging by Friction:
Charging by friction occurs when two different materials are rubbed against each other, causing a transfer of electric charge. This process is also known as triboelectric charging.
Electron Transfer:
Atoms are made up of positively charged protons, negatively charged electrons, and neutral neutrons. When two materials are rubbed together, their outermost electrons can be transferred from one material to another.
Charge Imbalance:
In the case of rubbing a glass rod with silk, the silk material has a higher affinity for electrons compared to the glass rod. As a result, electrons are transferred from the glass rod to the silk, leaving the glass rod with a net positive charge.
Positive Charge:
The glass rod gains a net positive charge because the loss of negatively charged electrons creates an imbalance of positive and negative charges. The glass rod now has an excess of positive charges (protons) compared to its negative charges (electrons).
Charge Conservation:
It is important to note that charge is always conserved in any charging process. The total amount of charge remains the same, but the distribution of charges changes due to the transfer of electrons.
Conclusion:
When a glass rod is rubbed with silk, it becomes positively charged because electrons are transferred from the glass rod to the silk. This creates an imbalance of positive and negative charges, resulting in a net positive charge on the glass rod.
