Unformatted text preview: α , the vertical intercept b and their uncertainties. DO NOT PLUGIN NUMBERS. Just write the formulas for the problem variables. 4. According to the lab manual, what is the expected value of e / m ? What about the uncertainty of that value? 5. The equation 2 2 2 B R V m e = is a relation describing the motion of a charged particle in a magnetic field. Suppose you have plotted R 2 vs. V. Use the aforementioned equation to show how the slope a of this graph relates to m , e and B . Solve for e/m . Give the uncertainty of e/m in terms of the remaining parameters....
