Michelle Garcia v (Student) Main Menu l Contents l Grades ll Hws Timer Notes a Evaluate Feedback Print o Info Course Contents An electron moving at 4.30x103 m/s a field experiences a magnetic force of 2.60x10 N. What angle does the velocity of the electron make with the magnetic field? There are two answers.

Explanation / Answer

F = qvbsin[angle]

sin [ angle ] = F /qvb = 2.6*10-16/1.67*10-19*4.3*103*1.27

sin[angle] = .2851

angle = 16.564 or 163.436
