Magnetic fields (urgent)
Hello, I'm in trouble, I have no idea what to do/look for the formula to solve these 2 questions.
Please help and guide
---------------------------------------------------------------------------------
A straight wire has a current of 15 A vertically upwards, in a vacuum. An electron, presently 0.10 m from the wire moves at a speed of 5.0 x 106 m/s. Its instantaneous velocity is parallel to the wire but downward. Calculate the magnitude and direction of the force on the electron. Will this force remain constant?
----------------------------------------------------------------------------------
A singly ionized atom of mass 3.9 x 10-25 kg is accelerated through a potential difference of 1.0 x 105 V.
a) Calculate its maximum speed.
b) What is the radius of the path it would take if injected at this speed and at 90 degrees into a uniform magnetic field of magnitude 0.10 T?
