Charge in the form of a plane sheet with density ρs = 40 μC/m2 is located at z = -0.5 m. A uniform line charge of ρl = -6 μC/m lies along the y axis. What net flux crosses the surface of a cube 2 m on an edge, centered at the origin?
What is the absolute permittivity of a substance?
What is the angle between two vectors, if their sum is to be maximum?
Take a glass rod, rub it with silk and hang it from a long silk thread. Take another glass rod, rub with silk and hold it near the rubbed end of the first rod. What happens to the rods?
