Why protons attract inside a nucleus?

What is the reason for proton- proton attraction inside the nucleus according to nuclear physics? (Sanjeev Asked) Answer: Inside the nucleus where the nucleons are very close to each other, the force which holds them together is the nuclear force, which is the strongest force in nature. The electrostatic force between protons is negligibly small … Continue reading Why protons attract inside a nucleus?

Electric field inside a dielectric

Why does the electric field inside a dielectric decrease when it is placed in an external electric field? (Thushara asked) Answer: The net electric field inside a dielectric decreases due to polarization. The external electric field polarizes the dielectric and an electric field is produced due to this polarization. This internal electric field will be … Continue reading Electric field inside a dielectric

Potential Difference

Pawan Asked "What is meant by potential difference?" Answer: "Potential Difference between two points is the difference in Potential between the two points and is equal to the work done per unit charge ion carrying a positive test charge from one point to another against the electric field and without any acceleration"
