An playing card is placed on top of a drinking glass, and a coin is placed on the top of the card. A student quickly flicks the card sideways off the glass, and the coin falls into the glass. Which of these explains why the coin falls into the glass rather than moving to the side with the playing card?
A Newton's First Law of Motion
B Newton's Second Law of Motion
C Newton's Third Law of Motion
D Newton's First Law of Universal Gravitation

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?
