GEOLOGY

Detailed explanation-1: -In this demonstration, a charged particle is brought close to but not touching the electroscope. The electrons in the electroscope are induced to move due to the presence of the charged particle above the plate of the electroscope.

Detailed explanation-2: -In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other. That is, a positively charged object will exert a repulsive force upon a second positively charged object. This repulsive force will push the two objects apart.

Detailed explanation-3: -When an uncharged object is placed very close to a charged conductor without touching, the nearer end acquires a charge opposite to the charge on the charged conductors and the two bodies attract. This is called charging by induction.

Detailed explanation-4: -Updated On: 27-06-2022. (i) Bring two metal spheres, A and B, supported on insulating stands, in contact as shown in figure (a). (ii) Bring a positively charged rod near one of the spheres, say A, taking care that it does not touch the sphere. The free electrons in the spheres are attracted towards the rod.

Detailed explanation-5: -When two charged objects are brought near each other, they attract or repel depending upon the type of charge they possess. If both the objects possess the same type of charge, they repel and if they possess the opposite charges, they attract.
