Asked by Lanise

An electron travels at a speed of 4.0×104 m/s through a uniform magnetic field whose magnitude is 1.4×10−3 T.

What is the magnitude of the magnetic force on the electron if its velocity and the magnetic field are perpendicular? F= N

What is the magnitude of the magnetic force on the electron if its velocity and the magnetic field make an angle of 45 ? F= N

What is the magnitude of the magnetic force on the electron if its velocity and the magnetic field are parallel?
F= N

What is the magnitude of the magnetic force on the electron if its velocity and the magnetic field are exactly opposite? F= N

You don't seem to be willing to take step one in answering these problems yourself.

You should have been taught the laws
F = q V x B and Ampere's law as part of your course work

q is the (negative) electron charge in this case.
