[SOLVED] [101] Magnetic field strength in fN
You have arranged that the magnetic field in a particular region of space is due North with a value of 0.01 T. An electron enters the field traveling to the West with a speed of 0.05 of the speed of light. As a result, the electron experiences a magnetic force which is upwards.
(a) What is the strength of this magnetic force, in fN? (NOTE: The "f" stands for "femto", which is 10-15.)
(b) What is the amount of the resulting acceleration of the electron? (NOTE: Get the mass of an electron from the inside back cover of your textbook.)
B=.01T
B=2ki/c^2r
F=ma
B will be very strait forward once I have answered a. I already know the strength of the magnetic force (B) in Tesla. So, it seems that I just need to convert tesla to femto Newtons. Can someone lead me in the right direction?
I am not very familiar with this concept.
Thank you SO much!
