State the reason. Why like charges repel while unlike charges attract
Answers
Answer:
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.
Like charges repel, unlike charges attract
Since the electron is much smaller and lighter than a proton, when they are attracted to each other due to their unlike charges, the electron usually does most of the moving. This is because the protons have more mass and are harder to get moving.
If the charges are similar – they repel. If the charges are opposite – they attract. If one is charged and the other is not – they attract.
