1. The problem statement, all variables and given/known data A magnetic field of 0.0200 T [up] is created in a region. a) Find the initial magnetic force on an electron initially moving at 5.00 E+6 m/s [N] in the field. b) What is the radius of the circular path? c) Make a sketch showing the path of the electron. Electron Charge = q = 1.6⋅10-19 Coulomb Constant = k = 9⋅109 2. Relevant equations F = qvB F = k ⋅Q ÷ r2 → r = √ k ⋅Q ÷ E ??? F = qvB = mv2/r a=qE/m 3. The attempt at a solution a) F = qvB = 1.6⋅10-19⋅5⋅106⋅2⋅10-2 = 1.6⋅10-14 b) r = √ 9⋅109 ⋅1.6⋅10-19 ÷ 1.6⋅10-14 = 314.6 I'm kinda confused as to the distinction between F = k ⋅q ⋅q ÷ r2 and E = k ⋅Q ÷ r2. I hope I used this right, but I'm finding lots of different answers... My answer seems way to large unless it is not in meters... I'm getting 314 so I think this is wrong. If it's wrong am I supposed to use F = qvB = mv2/r ? If this is true how am I supposed to use the rest mass of the electron? a=qE/m and F=qvb? F=ma ... ? For the diagram, I'm having trouble visualizing this. If you can help me understand what the diagram should look like... Extra kudos for a half tried paint brush image because I'm more a visual learner.
