Slader Two very extensive and very thin metal plates are parallel and close to each other. One is on the y-z plane at x = 0 and the other is parallel to the y-z plane at x = 1cm. The inner surface of the left plate is negatively charged and the inner surface of the right plate is positively charged. The magnitude of the surface charge density (σ) is 7.00 x 10-22 C/m2 on each plate. (a) Find the electric field (E) for points x < 0. (b) Find E for points 0 < x < 1cm. (c) Find E for points x > 1cm.

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.

You are driving directly behind a pickup truck, going at the same speed as the truck. a crate falls from the bed of the truck to the road. (a) will your car hit the crate before the crate hits the road if you neither brake nor swerve? (b) during the fall, is the horizontal speed of the crate more than, less than, or the same as that of the truck?

Suppose a wire with a current is pushed upward by a magnetic field. how would the wire move if the direction of the current reversed? explain your answer.
