Consider the electric field created by a very long charged line of negative linear charge density -2.50 nC/m. A small positive point charge of 12 mC moves from a distance of 7 cm to a distance of 18 cm. In mJ, how much work is done by the electric field? Hint: The electric ...

Consider three conducting spheres each 10 cm in diameter. A has a net charge of 5 C, B has a net charge of 10 C, and C has a net charge of zero, but is placed in an electric field of 1000 V/m. Rank the electric field strength inside the spheres from weakest to strongest.
