An object can be charged by friction when rubbed against another surface such as
a) polythene rod rubbed against a woollen cloth.
This occurred because the woollen cloth lost some of it negative charges when it was rubbed, the negative charges was then transferred to the polythene rod. Now the polythene rod has been charge by friction.
For proof... after it has been charged,place the polythene rod next to some *very small bits of paper and see what happens.
What else can I help you with?
Do you have to touch and object to permanently give it a charge?
No, you do not need to touch an object to permanently give it a charge. You can induce a charge on an object through methods like friction, conduction, or induction. This charge can persist on the object even after you remove your contact.
What is the charge that stays on an object called?
The charge that stays on an object is called static charge or static electricity. It occurs when there is an imbalance of electric charges on the surface of an object due to friction or contact with other charged objects.
Why is it more difficult to charge an object by friction on a humid day than on a dry day?
Humid air contains more water molecules that can dissipate excess charge away from the object being charged, reducing its ability to accumulate charge. This makes it more difficult to charge an object by friction on a humid day compared to a dry day.
In a neutral object has been charged by friction to a charge of one pC what has happened to it electrically?
Approx. 6.24 x 106 electrons have rubbed either onto it or off of it during the friction, leaving the net charge on it unbalanced by 10-12 coulomb.
What is the electric charge that has accumulated on an object it referred to what?
The electric charge that has accumulated on an object refers to an excess or deficiency of electrons on the object's surface, leading to a net positive or negative charge. This accumulation of charge can be influenced by various factors such as friction, induction, or conduction.

3 methods of charging an object?
Friction: Rubbing two objects together can transfer electrons, resulting in one object becoming positively charged and the other negatively charged. Conduction: Direct contact with a charged object can transfer charge to another object, bringing it to the same charge. Induction: Bringing a charged object near another object can cause electrons to be rearranged, creating an opposite charge on the objects.
What are the 3 methods of transferring a charge?
The three methods of transferring a charge are conduction, induction, and friction. Conduction is the transfer of charge through direct contact between objects, induction is the rearrangement of charges in an object caused by a nearby charged object without direct contact, and friction is the transfer of charge between two objects through rubbing them together.
What are the three ways by which static charge is produced?
Static charge is produced through friction, conduction, and induction. Friction occurs when two materials rub against each other, transferring electrons and creating a charge. Conduction happens when a charged object comes into direct contact with a neutral object, transferring charge between them. Induction involves a charged object creating a charge in a neutral object without direct contact, by causing the electrons to rearrange within the neutral object.
Can an object get charged from stretching?
No, stretching an object will not cause it to become electrically charged. Charging an object requires the transfer of electrons. Stretching changes the shape or size of an object but does not result in the accumulation of electric charge.
What are three ways objects acquire charge?
Objects can acquire charge through friction, conduction, and induction. Friction involves two objects rubbing together and exchanging electrons. Conduction occurs when a charged object comes into direct contact with another object, transferring charge. Induction involves bringing a charged object near another object, causing a redistribution of charges within the object.
How is the charge on a charged object maintained?
The charge on a charged object is maintained by the movement of electrons within the object. If electrons are added or removed from the object, its charge will change. Charging methods such as friction, conduction, or induction can alter the charge on an object.
