Physics, asked by liaente, 11 months ago

It says "if a charged object is brought near to an uncharged object, it can attract it"

Is a charged object either + or - and does an uncharged object have no + or - but neutral? If so, how does that work? I've been taught only unlike charges attract, meaning
- and +. So how is an uncharged object able to be attracted?

This happens by induction /polarization.

liaente: Could you please explain what you mean by that?

Physicsmaniac: Sure see the image first.

liaente: Ah I kind of get it, so please answer, in essence - is an uncharged object neutral or have - or + ?

Physicsmaniac: It's neutral having equal number of electrons and protons.

Physicsmaniac: Can you please mark my answers as brainliest.

liaente: Thank you :) So how is it attracted if unlike charges attract? I thought it only worked for positive and negative.
Yes ^^ after this last Q.

Physicsmaniac: Since "neutral" objects are made out of many positive and negative charges in equal measure, some of which can move, if the charged body taken is positive it will attract electrons of the uncharged body towards itself.This will lead to accumulation of -ve charge on nearby surface and +ve charge on distant surface of the neutral body.

Physicsmaniac: Now,force of attraction between the charged body and -ve surface (nearby)will be more than force of repulsion between the charged body and +ve surface (distant) leading to a net attractive force.The difference in magnitude of the two forces is because Colombian/electrostatic force is inversely proportional to square of distance between the charged.

liaente: Thanks so much! Marked as brainliest :)
