(7 points) One way to administer flea medication to an animal is to drop medicine behind their neck. The fumes from the oily fluid kills fleas living on them. Imagine a 2 miligram flea running from these fumes through the fur of a large dog, collecting a net charge through friction equal to -100 nC. The flea then jumps horizontally with speed of 1.9 m/s off the dog into a 200 N/C electric field created by the Earth that points down and towards them at an angle of 20° (a) Is the flea in the air (time of flight) longer with the electric field present, not present, or does it not make a difference? Explain using words, figures, math, or other representations. (Ignore air resistance) (b) What is the acceleration vector of the flea after it jumps off the dog, while it is in the air (ignore air resistance). (©) Extra Credit (up to 3 pts): How far does the flea fly horizontally when the electric field is present? The flea is initially 1.00 meters above the horizontal ground. V 10 É
