A positively charged body can attract another positively charged body. what is the reason behind it. explain the process
Answers
Answer:
Explanation:If the two bodies are placed close to each other where one has much more charge than the other, then due to induction, force of attraction becomes more than the force of repulsion.

Yes…two positively charged bodies can attract each other under the phenomenon of electrostatic induction. For that the following two things needs to be done.
One of the bodies should be significantly larger than the other one.
They has to placed very close to each other.
Once they are placed close to each other induction takes place which causes the electrical charges to redistribute in the smaller body resulting one side having an excess of negative charge ( the side which is closer to the larger body) and the other side with positive charge ( the side which is distant from the larger body) hence they ended up attracting each other.
Generally, they repel each other and it is true for all distances more than the order of 10−15m
But in a special case, like the nucleus of an atom a special kind of force, which is the strongest type of force in the universe, known as Nuclear Force or Binding Force takes over.
They are much stronger than even electrostatic forces or coulombian forces. But they come into effect only at distances of the order 10−15m (known as femto metres), even then their existence is wiped beyond a few femto metres( about 3.5 fm). These forces oppose the electrostatic repulsion and binds the huge number of protons and neutrons together in such a small space of only a few femto metres in the Nucleus of an atom. However, a fun fact is that at distances less than 0.8fm nuclear forces turn repulsive and at distances slightly more or equal to 0.8fm they are the strongest attractive forces in nature.
SO, to answer your original question nuclear forces are not electrostatic forces so should not be technically considered as positive charges attracting each other due to the property of their charge, rather it should be considered as the positive charges attracting each other by the virtue of the distance between them.
Hope this helped!
