True or false? the surfaces of equal potential around an infinite charged plane are parallel to the plane (i. e. the surfaces never intersect the charged plane). false true [5 points] suppose i center a conducting sphere of charge (radius r, total charge +q) at the origin. how much energy would it take to move a point charge (total charge +q) from the surface of the sphere (r = r) to the center of the sphere (r = 0)? e = kq / r

Which configuration would produce an electric current? a) rotate a coil of copper wire between two magnets. b) connect a wire between a copper and zinc strip sitting in a beaker of water. c) connect a wire to the (+) positive end of a battery and the other end to a light bulb. d) connect a wire to the negative end of a battery and the other end to a light bulb.

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.
