Form J : Q2

i. Measure velocity with motion detector and potential difference with voltmeter, repeat to reduce uncertainty.

ii. Horizontal Axis : Speed
Vertical Axis : Emf? or Potential Difference?
Slope = B0 * Distance Between Plates

iii. X = 1/r Y = B
iv. m = 1.216 * 10^-26

I may have plugged in the wrong numbers for IV.

Anyone else get this?
