Question

Why do always like charges repel and unlike charges attract each other?

Answer 1

in case of this the like charges repel and unlike charges attract each other .because in like charges the magnetic power is more and the charges are same and equal.so the like charges are repel.....

incase of unlike charges...they attract each other because the charges of magnets are not same and not equal .so the unlike charges attract each other.......

Answer 2

Hi friend,

Objects can be positively charged, negatively charged or neutral (no charge).

A substance that gains electrons becomes negatively charged, while a substance that loses electrons becomes positively charged.

When a charged object comes near to another object they will either attract or repel each other.

If the charges are the same - they repelIf the charges are opposite - they attractIf one is charged and the other is not - they attract

Like charges repel. Unlike charges attract.

Now as quantum mechanics suggests that attraction and repulsion is because of virtual transfer of photons.And it is obvious that positively charged particles will have photons in excess i.e, positive charge is more so when 2 like charges contact each other both the charges tend to transfer their virtual photons between themselves as a result of this electrostatic force of repulsion acts between the 2 positively charged particles and they repel each other.

OPPOSITE CHARGES ATTRACT:-

As positively charged particles have excess of virtual photons and negatively charged particles are photon deficient both the particles will tend to attract each other as positively charged particle will tend to transfer its virtual photons to negatively charged particle and it will tend to accept those virtual photons.Thus, electrostatic force of attraction is created and they attract each other.
