A uniformly loaded plastic rod measuring 9.2 cm in length is sealed inside a plastic bag. The total flow out of the bag is 9.7 * 105 N.m2 / C. What is the linear charge density of the rod? (in micro Coulombs on the meter)

Two metal rods, vertically placed and separated, are joined at the top. a distance of l = 50cm. The whole, whose resistance is considered contempt- It is placed within a uniform magnetic field of flow density B = 0.01kT perpendicular to the plane defined by the rods. By them, it slides downwards with constant speed of v = 1jm / s, without friction and without interrupting the contact, a bar AB whose mass is m = 1g. Determine the resistance...
