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

When a polythene piece is rubbed with wool, it acquires negative charge. Is there a transfer of mass from wool to polythene?

A polythene place is rubbed with wool. It is found to acquire a negative charge of 3.2 xx 10^(-7) C.Estimate the number of electrons transferred to the piece.

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?

When a glass rod is rubbed with a silk cloth, charges appear on both. A similar phenomenon is observed with many other pairs of bodies. Explain how this observation is consistent with the law of conservation of charge.

When a glass rod is rubbed with a silk cloth, charges appear on both. A similar phenomenon is observed with many other pairs of bodies. Explain how this observation is consitent with the law of conservation of charge.

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. When a glass rod is rubbed with silk, it acquires a positive charge becuause:

A polythene piece rubbed with wool is found to have a negative charge of 3 xx 10^-7 C . Is there a transfer of mass from wool to polythene?
