1. The problem statement, all variables and given/known data An electron moves in a circular path in a vacuum under the influence of a magnetic field perpendicular to and into the paper.If there is another electron which moves with a higher speed in a circular path in the same B-field, state and explain how each of the following will be affected as compared to the first electron? (c) The radius of the circular path 2. Relevant equations F = Bqv B = flux density q = charge v = velocity of the charge 3. The attempt at a solution F(m) = Bqv Since F(m) causes the centripetal acceleration of electron F(m) = Bqv = mv^2/r r = mv/Bq Therefore it can be concluded that r increases as v increases? But how can this be case as, F(m) = Bqv, and F(m) increases as velocity of the charge increases If F(m) increases, r would decrease as it is inversely proportional to F in the equation F(m) = mv^2/r. So would r increase or decrease if a faster electron moves in a circular path in a vacum under the influence of a magnetic field perpendicular to and into the paper.
