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?

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...
