The print size for the body of a newspaper is around 8-9 point. At this size, a reader would need to discern parts of the text that are as close as 100 microns, or 0.0001 meters. What is the farthest distance that the average person could hold the paper from their face and still comfortably read the text. a. 100 cm b. 66 cm c. 30 cm d. 10 cm

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?
