Nvm close pls

Actually still need... Paying 25fg per parts. Please show your work. Im looking to learn how to do these as well.


An electron travels at a speed of 5.0×104m/s through a uniform magnetic field whose magnitude is 1.4×10−3T .

Part A
What is the magnitude of the magnetic force on the electron if its velocity and the magnetic field are perpendicular?
Express your answer using two significant figures.

Part B
What is the magnitude of the magnetic force on the electron if its velocity and the magnetic field make an angle of 45 ∘?
Express your answer using two significant figures.

Part C
What is the magnitude of the magnetic force on the electron if its velocity and the magnetic field are parallel?
Express your answer using two significant figures.

Part D
What is the magnitude of the magnetic force on the electron if its velocity and the magnetic field are exactly opposite?
Express your answer using two significant figures.

F=qV x B
that is charge of electron times velocity cross the B field vectors
will be used for all your questions . part a is simply plug in others will require you to understand cross product

Thanks i got it but i am struggling on Part B. Got Part A, C, D but B.. Keep getting weird numbers..

post what you have done. your work , steps
