A. We can increase the applied B field by increasing the coil current. First predict what will change in the path of the electron when the B field is increased.B. Now turn up the coil current and watch the beam. Describe any changes in the path. Can you explain why the path changed in this way?C. Our beam of electrons is moving in a circle so our acceleration is centripetal acceleration (v2/R) where R is the radius of the circle. Our force is then:F = qvB = mv2/RSolve this equality for R in terms of q, v, m and B and write the equation below, R = ?
