Expert Solution

Figure (a) :::   V = - 3*10^7 y^

                         B = 0.3 x^

                          q = charge on electron = -1.6*10^-19 c

                        F = force

                        F = qV x B

                             = qVB

                             = 1.6*10^-19 * 3*10^7 *0.3

                             = 1.44*10^-12 N



forgure (b)   V = 3*10^7 [ - cos(45) y^ + sin(45) z^]

                     V = 2.12*10^7 [ - y^ + z^]

                   B = 0.3 x^

                          q = charge on electron = -1.6*10^-19 c

                    

                     F = qV x B

                        = q*2.12*10^7 [ - y^ + z^] x   [ 0.3 x^ ]

                        = q * 2.12*10^7 * 0.3 [ z^ + y^]

                        = 1.6*10^-19* 2.12*10^7 * 0.3 [z^ + y^ ]

                       =1.017*10^-12 [z^ + y^ ]


              magnitude = 1.017*10^-12 * sqrt(2) = 1.43*10^-12 N
