Avery small red laser pointer is pointed on the wall across the room. when inspecting the reddish light on the wall, you notice that it is because it has been diffracted. a) bent b) brighter c) spread out d) bounced back

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?
