Explanation:
Like charges attract each other:
- This statement is not correct as like charges actually repel each other due to the principle of electrostatic force.
- According to the law of electrostatics, opposite charges attract each other while like charges repel each other.
Electric charge obtained by rubbing materials against each other is static:
- This statement is correct as when two materials are rubbed against each other, electrons are transferred from one material to the other, creating a static electric charge.
Electricity is generated by the movement of charge:
- This statement is correct. Electricity is generated when charges move through a conductor, creating an electric current.
The charge from any charged object is sent to the earth by earthing:
- This statement is correct. Earthing is a process used to safely discharge electric charges from an object to the ground, preventing any potential harm from electric shocks.
Therefore, the correct answer is option 'A' as like charges repel each other, not attract.
