Question

In the figure, an electron with an initial kinetic energy of 4.10 keV enters region 1 at time t = 0. That region contains a uniform magnetic field directed into the page, with magnitude 0.00550 T. The electron goes through a half-circle and then exits region 1, headed toward region 2 across a gap of 23.0 cm. There is an electric potential difference ΔV = 2000 V across the gap, with a polarity such that the electron's speed increases uniformly as it traverses the gap. Region 2 contains a uniform magnetic field directed out of the page, with magnitude 0.0247 T. The electron goes through a half-circle and then leaves region 2. At what time t does it leave?
