Electric field between 250 m high and 200 m thick cloud and the surface of earth is 130 v/m directed vertically. At the top of the cloud is +q and the bottom of cloud is –q making the cloud neutral. Calculate the magnitude of the external electrical force on the cloud.
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...
6. There is an electric field close to the surface of Earth. This field points toward the surface and has a magnitude of about 1.5 x 102 N/C. A charge moves perpendicularly toward the surface of Earth through a distance of 439 m, the height of the Sears Tower in Chicago, Illinois. During this trip, the electric potential energy of the charge decreases by 3.7 x 10s J. a. What is the charge on the moving paride? b. What is...
