An electron of mass 9.11 10-31 kg has an initial speed of 3.80 105 m/s. it travels in a straight line, and its speed increases to 7.60 105 m/s in a distance of 4.20 cm. assume its acceleration is constant. (a) determine the magnitude of the force exerted on the electron. 0.82875492 incorrect: your answer is incorrect. your response differs from the correct answer by more than 10%. double check your calculations. n (b) compare this force (f) with the weight of the electron (fg), which we ignored. f fg =
