An electron moves with an unknown velocity through a magnetic field of 1.56 T that points directly east. The electron experiences a force of 6.24 x 10^-15 N directly south. What is the magnitude and direction of the velocity? Show your work. (The charge of an electron is -1.6 x 10^-19 C)

the answer is c i did the same question so i know that's right!

prolly a beacuse the momentuem the car has increases while going down hill

i had this question and the answer was 3.15 miles.
