In the x-y-plane
In the x-y-plane, the region y>0 has a uniform magnetic field B 1 k ^ and the region y<0 has another uniform magnetic field B 2 k ^ . A positively charged particle is projected from the origin along the positive y-axis with speed V o = π m/s at t = 0, as shown in the figure. Neglect gravity in this problem. Let t = T be the time when the particle crosses the x-axis from below for the first time. If B 2 =4B 1 , the average speed of the particle, in m/s , along the x-axis in the time interval T is ________.
