Question

What do you mean by charging by induction?​

Answer 1

• When a charged body comes closer to an uncharged body but without physical contact, then closer end of the uncharged body facing the charged body facing the charged body attains opposite charge as that of the charged body.
• On the other hand, the farther end attains the same charge as that of the charged body. This method of charging by induction.

Answer 2

$\mathtt{\huge{\underline{\pink{Answer :-}}}}$

Electrostatic induction is the phenomenon of temporary electrification of a conductor in which opposite charges appear at its closer end and similar charges appear at its farther end in the presence of a nearby charged body.

Process :-

(a) Take the metal sphere on an insulating stand. Bring a negatively charged plastic rod near it. The free electrons of the sphere are repelled to the farther end. The near end becomes positively charged due to deficit of electrons.

(b) When the far end of the sphere is connected to the ground by a connecting wire, its free electrons flow to the ground.

(c) When the sphere is disconnected from the ground, its positive charge at the near end remains held there due to the attractive force of the external charge.

d) When the plastic rod is removed, the positive charge spreads uniformly on the sphere.

Hence , the spherical rod gets positively charged.
