lab 4 preparation

1. q*v*(B*sin(theta))
2. towards, away from
3. The magnitude of the magnetic field at the black dot is smaller than its value at the upper end of the bar , The magnitude of the magnetic field just above the upper end of the bar is equal to its value just below the lower end of the bar, The magnetic field at the black dot points up
4. diagram a .. along + y for a positive ion, along - y for an electron ....... diagram b .. along - y for a positive ion
5. B*A*cos(theta) ... -(DeltaPhi/Deltat)
6. V_2/V_1
7. .3 V ... .001166 s ... frequency is 1/Period and units are Hz

How did u calculate the peak to peak amplitude and the period??
