A high-voltage transmission line is made of bare wire; it is not insulated. Assume that the wire is 100 kmkm long, has a resistance of 7.0 ΩΩ, and carries 200 A. A bird is perched on the wire with its feet 2.0 cm apart. What is the potential difference between its feet?

Four objects each with charge +2.0×10−7c are located at the corners of a square whose sides are 2.0 m long. part a what quantities can be determined using this information? check all that apply. the electric force on a charged object placed at the center of the square. the mass of each object. the total electric potential energy of the system consisting of the four charged objects. part b find the electric force on a charged object placed at the center of the square.
