Which of the following can be charged by friction if held by hand?

Which of the following can be charged by friction if held by hand?

B. All of the above substances are insulators whereas Copper rod is a conductor. As soon as we charge a copper rod by rubbing with another material, the electric charge flow through our hand and body and flows into the earth. As a result, the copper rod remains un-charged.

How will you charge plastic scale by the method of friction?

1) The charging of a glass rod by rubbing it with a silk cloth. 2) When a plastic comb is rubbed with dry hair, the plastic comb acquires an electric charge due to friction. 3) When a ball point pen refill is rubbed vigorously with a piece of polythene, the refill acquires electric charge by friction.

Which of the following Cannot be charged by friction if held by hand?

Only non-conducting materials can be charged by friction, and copper is a conducting material. Hence, it can’t be charged by friction.

What materials Cannot be charged by friction?

Copper, being a good conductor, cannot be charged by friction. Q3.

Which of the following object Cannot be charged by rubbing?

silk clothes and silk clothes will not get charged on rubbing.

Can conductors be charged by frictional rubbing?

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. electrons of the can are pushed away from the rod.

When an object gets negatively charged by the process of friction then?

When an object gets negatively charged by the process of friction, then C. the object gains some electrons. Explanation: A matter is charged by three process such as charging by induction, charging by contact and charging by friction.

Which of the following Cannot be charged easily by friction * 1 point a plastic scale a copper rod an inflated balloon a Woollen cloth?

The answer is d, coppr rod, which means the copper rod cannot be charged by friction because both it is a highly conducting material. As only nonconductive materials can be charged by friction highly conductive copper rod cannot be charged by friction.

What materials can be charged by friction?

The prefix tribo- (Greek for ‘rub’) refers to ‘friction’, as in tribology. Other examples of materials that can acquire a significant charge when rubbed together include glass rubbed with silk, and hard rubber rubbed with fur.

How can an object be charged by friction?

When insulating materials rub against each other, they may become electrically charged . Electrons , which are negatively charged, may be ‘rubbed off’ one material and on to the other. The material that gains electrons becomes negatively charged. The material that loses electrons is left with a positive charge.

Why can plastic become charged if u rub it but not metal?

Explanation: When you rub plastic, you transfer electrons from one material to the other. Because plastic is an insulator, the electrons cannot flow through it so they effectively get stuck there – they are static. In a metal, the electrons would get conducted away (e.g. back to the material they have come from).

How do objects get charged due to rubbing?

As soon as it gets charged by rubbing with another material, the electric charge produced on its surface flow through our hand and body into the earth and it remains uncharged. This video describes how the objects get charged due to rubbing. Study of transfer of charge & generation of static electricity by induction…

What is the charge on the glass rod and straw?

A charged glass rod has a positive charge on its surface and a charged plastic straw has a negative charge on its surface. (c) This statement is False. The lightning conductor is a device which is used to protect a tall building from lightning. (d) This statement is False.

Which object becomes negatively charged when rubbed with a woollen cloth?

The rubber balloon becomes negatively charged when rubbed with a woollen cloth. The woollen cloth acquires a positive charge. 9. Name the device to detect electric charge on a body. The electroscope is the device which is used to detect charge on a body.

What is the difference between charged and uncharged objects?

An object having an electric charge on it is called uncharged object and that of having an electric charge is called charged objects, an example is that a glass rod is rubbed with a silk cloth. Glass rod which was electrically neutral at initial and acquire electric charge on rubbing with a silk cloth.
