Charging Methods and Effects

The video tutorial covers the concepts of electric charge and methods to charge neutral objects, including conduction, induction, and grounding. It explains charging by conduction with examples of rubber and glass rods, where contact leads to electron transfer. Charging by induction is demonstrated using metal spheres, highlighting charge separation without contact. The tutorial also explores induction combined with grounding to charge a single sphere, resulting in an opposite charge to the inducing rod.

What are the three methods mentioned for charging neutral objects?

• Conduction, Induction, and Radiation

• Conduction, Induction, and Abduction

• Conduction, Induction, and Convection

• Conduction, Induction, and Grounding

In charging by conduction, what happens when a charged object touches a neutral object?

• The neutral object becomes negatively charged

• The neutral object remains neutral

• The neutral object acquires the same charge as the charged object

• The neutral object becomes positively charged

What happens to a pith ball when a negatively charged rubber rod is brought near it?

• It becomes positively charged

• It loses all its electrons

• It becomes negatively charged

• It remains neutral

When a glass rod rubbed with silk is brought near a neutral pith ball, what charge does the pith ball acquire?

• Both positive and negative charges

• No charge

• Negative charge

• Positive charge

In charging by induction, what is the role of the charged object?

• It transfers electrons directly

• It remains distant and causes a separation of charge

• It touches the neutral object

• It becomes neutral

What happens to the two metal spheres when a negatively charged rod is brought near one of them?

• Both spheres remain neutral

• Both spheres become positively charged

• Both spheres become negatively charged

• One sphere becomes positive, the other negative

What is the result of pulling the two spheres apart while the charged rod is still near one of them?

• The spheres lose all charges

• Both spheres become neutral

• Both spheres acquire a net charge

• The spheres exchange charges

In charging by induction and grounding, what role does the ground play?

• It removes electrons from the sphere

• It has no effect on the sphere

• It adds electrons to the sphere

• It neutralizes the sphere

What happens to the sphere when the negatively charged rod is removed after grounding?

• The sphere becomes negatively charged

• The sphere becomes positively charged

• The sphere loses all its charge

• The sphere remains neutral

When charging by induction and grounding, what charge does the neutral object acquire compared to the charged rod?

• The same charge

• Both charges

• No charge

• The opposite charge
