The magnetic field shown in the figure consists of two uniform regions. The width of the first part is 5cm and the magnetic induction here is `0.001` T. The width of the other part is also 5cm, with the direction of the induction being opposite in direction and `0.002` T in magnitude. What should be the minimum speed of the electron arriving from the direction indicated in the figure so that it can pass through the magnetic field? Mass of electron `=9xx10^(-31)`kg
