When the glass rod is rubbed with silk, the silk strips electrons from the rod, leaving it a positive charge. When the hard rubber rod is rubbed with wool, it gains electrons from the wool, gaining a negative charge.

Glass rod becomes positively charged and silk becomes negatively charged. For example, suppose a glass rod has 10 protons and 10 electrons and silk has 7 electrons and 7 protons. On rubbing together, the glass rod loses 2 electrons and silk gains 2 electrons.

When woolen cloth is rubbed against the plastic, both wood and plastic get electrified due to friction produced while rubbing. So, plastic has greater electron affinity (ability to attract electrons) as compared to wool, therefore, plastic acquires negative charge and wool acquires positive charge.

Touching the glass to the ball causes electrons to flow from the ball to the glass, as the electrons on the ball are attracted to the positive charge of the glass. Then the glass rod is rubbed with the wool, and the wool sheds electrons onto the glass, giving it a negative charge.

Hint: Glass rod acquires a positive charge due to transfer of electrons from the glass rod to the Silk cloth, which becomes negatively charged. Charge can neither be created nor be destroyed it is conserved in nature it can only transfer in integral amounts.

When the glass rod is rubbed with silk clothes, glass quickly loses electrons, and silk takes electrons out of the glass rod. So after rubbing, the glass rod becomes positively charged and the silk gets negative charge.

the glass rod acquires a positive charge due to loss of electrons. the silk cloth acquires negative charge due to gain of electrons.

1)As an example of the friction method, a glass rod rubbed with fur becomes negatively charged, but if rubbed with silk, becomes positively charged. 2)When you are rubbing the glass rod with the silk cloth, electrons are stripped away from the atoms in the glass and transferred to the silk cloth.

(iii) Yes, there will be a transfer of mass of 12 electrons from glass rod to silk.

When you are rubbing the glass rod with the silk cloth, electrons are stripped away from the atoms in the glass and transferred to the silk cloth. This leaves the glass rod with more positive than negative charge, so you get a net positive charge.

On rubbing together,fur loses 2 electrons and the 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.

No, there will be no effect on the mass of glass rod …. As we know , during rubbing of silk on glass rod Silk looses electrons nd aquires positive charge …

If two objects are rubbed together, especially if the objects are insulators and surrounding air is dry, the objects acquire equal and opposite charges and an attractive force develops between them. The object that loses electrons becomes positively charged. The other that gains electrons becomes negatively charged.

There are two main types of electricity, Static Electricity, generated by rubbing two or more objects causing to build up friction, Current Electricity, generated by the flow of electrical charge through a conductor across an electrical field.

Insulators can be easily charged by friction as the extra electrons gained CANNOT easily escape. Conductors: materials that allow electrons to flow through them easily. Conductors CANNOT be easily charged by friction as the extra electrons gained can easily escape.

But conductors ( like metallic rod ) can not be charged by the rubbing because the have free electrons due to the movement of these free electron in side the conductor the charge will not stay at a position hence the conductor will not attained any charge.

When a charged object is used to charge a neutral object by conduction, the previously neutral object acquires the same type of charge as the charged object. So in this case, both objects have a negative charge. 2. A neutral metal sphere is touched by a negatively charged metal rod.
