Why does an ebonite rod get negatively charged on rubbing with fur?

A charged ebonite rod is held near an insultated copper rod as shown in the figure. The electrons move away from the end A of the copper rod, leaving a positive charge there. Why does the movement of electrons ultimately come to a stop?

An ebonite rod is rubbed with fur/wool. What type of charges do they acquire?

Frictional electricity The electricity developed in bodies when they are rubbed with each other is called frictional electricity. There are two kinds of charges, namely positive and negative. Like charges repel each other and unlike charges attract each other. when a glass rod is rubbed with silk cloth, glass rod becomes positively charged are silk acquires the same amount of negative charge. the concept of positive and negatice charges was introduced by Benjamin Franklin. The charge is always quantised and conserved in a system. A body can be negatively charged by
