In Fig. 2, an electron with an initial kinetic energy of 5.0 keV enters region 1 at time t= 0. That region contains a uniform magnetic field directed into the page, with magnitude 0.010 T. The electron goes through a half circle and then exits region 1, headed toward region 2 across a gap of 25.0 cm. There is an electric potential diference AV= 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 0.020 T. The elctron goes through a half circle and then leaves region 2. At what time t does it leave?

A long, rectangular loop of width w, mass m, and resistance R is at rest, with the plane of the loop parallel to the ground. Immediately to the left of the loop is a region of uniform magnetic field B→ that points out of the screen.
