6. A book sits on the edge of Sammy's desk. What type of energy does the book have? Potential energy because it could fall to the floor.
Kinetic energy because it could be moved.
Potential energy because it is not moving,
Kinetic energy because it is heavy.

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
