← A point charge sits at the centre of a hollow sphere. The charge is then moved to a point inside the sphere, close to its wall. What happens to the net flux through the sphere?A thin, very long line of charge has 6.8 nC for every metre of its length. How strong is the field at a point 0.55 m from the line? →
