1) A -1 nC charge is placed in a uniform electric field of strength 25 N/C. What force (in N) (magnitude and direction) will the charge feel due to this field? 2) A + 1 C charge is placed at the origin. A -1 C charge is placed at position (x,y)=(2 m, 0), and a -2 C is placed at (x,y)=(1 m, 1 m). What is the electric potential energy (in J) of this charge configuration?
6 of 9 > there is an electric field Constants Learning Goal Part C To understand the behavior of the electric field at the surface of a conductor, and its relationship to surface charge on the conductor Assume that at some point just outside the surface of the conductor, the electric field has magnitude E and is directed toward the surface of the conductor. What is the charge density n on the surface of the conductor at that point? A...
At the earth’s surface there is a measurable electric field of 150 N/C that is directed down (towards the center of the earth). This implies that the solid part of the planet (from the surface to the core) has a net electric charge. Assuming that earth is a conductor, calculate (a) the sign of this charge (+ or –), (b) the surface charge density, (c) the total surface charge of the earth and (c) the number of elementary charges that...
A region has a uniform electric field of 5.5 x 105 N/C pointing straight up. A nickel that is initially uncharged is placed into this same region oriented horizontally. (The diameter of a nickel is 21 mm.) Being made of metal, the nickel will develop surface charges that cancel out the field in its interior (a) Find the charge density on each face of the nickel HC/m2 (b) Find the total charge on each face nc
