Question

1). At one instant an electron is moving in the xy plane. The components of its velocity are vx = 35816380.7 m/s and vy = 76506353m/s. A magnetic field of 7331.7T is in the +z direction. What is the magnitude of the magnetic force on the electron at that instant?

2). An electron and a proton are traveling with the same speed. The magnetic field is zero at the midpoint between them. This means:
A. they are traveling along perpendicular lines that intersect
B. they are traveling along parallel lines, in the same direction
C. they are traveling along parallel lines, in opposite directions
D. they are are traveling along the same line
E. they are traveling along perpendicular lines that do not intersect
