Every system has a tendency to lower it's energy.
For a system of 2 like/unlike charges (q1,q2), the energy of the system is given by the equation
U=k(q1)(q2)/r
where U=potential energy
k=constant for a medium(medium is one in which charges are kept eg air, water etc.)
q1,q2=charges(including their sign, positive or negetive)
r=dist. between charges
For U to be minimum, r should be maximum, everything else kept constant.
therefore, like charges move away to increase r.
Incase of unlike charges one will be negetive and other positive. Let q1 be negetive, so U=k(-q1)(q2)/r
Now, for U to be minimum, r should be minimum so charges attract.
Hence like charges repel and unlike attract

What are the two like charges?
a positive and a positive or a negative and a negative. Object with the same charge. Like charges repel each other.
How do like electric charges react to each other?
Electric charges that are the same (positive-positive or negative-negative) repel each other, while charges that are different (positive-negative) attract each other. This is described by Coulomb's law, which states that the force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
What happens when two negative objects are brought together?
When two negative objects are brought together, they will typically repel each other due to their like charges. This is because negative charges have the same polarity and repel each other according to the principles of electrostatics.
Do north pole and north pole repel each other?
Yes, in physics, like magnetic poles repel each other. This is known as the Law of Magnetic Poles. The same poles, such as two north poles, will repel each other because they have similar magnetic fields.
If you charge two nylon strings together with the same positive charge and then bring them together what do they do?
They will repel. Like charges repel, unlike charges attract. Theoretically anyway... if the 2 nylon strands are both positive, then physics dictates that they will repel, because like charges repel, so in otherwords, + repels from +, but is attracted to - and vice versa.
What happens when two charges are the same?
When two charges are the same (both positive or both negative), they repel each other due to the electric force. This force pushes the charges away from each other, as like charges repel.
What will happen to the objects with the same charges that are placed near to each other?
A repulsive force would exist as like charges always repel each other.
When 2 objects have the same charge do they attract each other?
When two objects have the same electrical charge, they repel each other.
How do like electric charges react other?
Like electric charges - charges of the same sign - repel each other.
When two objoects have the same charge do they attract each other?
No, objects with the same charge repel each other due to the electrostatic force. Like charges repel, while opposite charges attract.
Can two balls having the same kind of charge attract each other?
No, two balls with the same charge will repel each other. Like charges repel, while opposite charges attract.
What is meant by opposite charges attract?
Its meant that positive charges and negative charges attract each other and same sign charges repel each other.
How do like charges behave?
Like charges repel each other due to the electromagnetic force. This means that if two charges have the same sign (positive or negative), they will push each other away. This behavior follows the principle that opposite charges attract while like charges repel.
Would 2 protons attract or repel each other?
"Opposites attract". So two electrons repel each other.
What are the two like charges?
a positive and a positive or a negative and a negative. Object with the same charge. Like charges repel each other.
Will positive and positive repel or attract?
'Like' charges (both positive or both negative) repel.Unlike charges (one of each) attract.
What kinds of charges repel?
Like charges, such as two positively charged particles or two negatively charged particles, repel each other. This is because they have the same type of charge, creating a force that pushes them away from each other.
