When a proton and an electron are 1 cm apart, how do they interact?
They attract each other with an electric force.
Why do we define the charge on a proton as positive and on an electron as negative?
As a convention without indicating one charge is 'more' than the other.
Why is charge considered quantized according to the discussion?
Due to the observation that all observable charges are integral multiples of the elementary charge e.
What is the SI unit of charge and how is it defined?
Coulomb; It is the charge that flows through the wire in 1 s if the electric current is 1 A.
Learn about electric charge and elementary particles like electrons, protons, and neutrons. Understand how these particles interact with each other and the concept of gravitational forces.
