for the status defined,magnetic field B = (2t^3 – 4t^2+1) varies in T form and is r=2R=5cm.a) Calculate the direction and size of the force that is activated as soon as the electron t=2s is located in P.b) At what time does this force equal zero?
An electron travels at the speed of 23 x 10^6 m/s in a circular radius and 37 degrees inclined about the nucleus. Determine the distance away, about the nucleus if the magnetic field is 2 T?
Assuming that the radius of the circular path of the electron is 4.9cm when voltage is 100v and coil current is 1A and The Helmholtz coils have 130 turns and a radius of 15 cm. With N=130 and R=0.15
What is the magnetic field where the electrons are traveling that results from this 1 A current in the Helmholtz coils? Hint: Evaluate the expression given for the field betwee two Helmholtz coils with the dimensions used in the experiment.
Provide a numerical answer with no units, simply the field in "microtesla", that is in 10-6 T. For example, if you found 3.4 x 10-4 T, answer "340".
