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?
Where is electricity stored after it is generated but before it is supplied? Mahesh Sable Electrical power cannot be stored and,therefore,power plants must produce power as and when demanded.power stations r connected in parallel hence load is equally distributed,electric Power can be adjusted with help of step up or step down transformers. Mathew Abraham…… Continue reading Where is electricity stored after it is generated but before it is supplied? (Chat Transcript from FaceBook)
Can you answer these? A bullet of mass m is fired with a velocity v and strikes a a block of mass M suspended by a string of length L. the bullet gets embedded in the block.

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
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”
