← A point charge at the centre of a sphere gives a net flux of Φ through the sphere. The radius of the sphere is tripled, and a second charge equal to the first is placed at the centre. What is the net flux now?A proton is released close to a large flat sheet with a uniform positive charge, and it moves away from the sheet. What happens to the force on the proton as it goes farther from the sheet? →
