A uniform 5.5 T magnetic field points north. If an electron moves vertically downward (to- ward the ground) with a speed of 3.1 × 107 m/s through this field. The charge on a proton is 1.60×10−19. a) What is the magnitude of the force acting on it? Answer in units of N.
In the figure, an electron with an initial kinetic energy of 3.50 keV enters region 1 at time t = 0. That region contains a uniform magnetic field directed into the page, with magnitude 0.00910 T. The electron goes through a half-circle and then exits region 1, headed toward region 2 across a gap of 22.0 cm. There is an electric potential difference ?V = 2000 V across the gap, with a polarity such that the electron's speed increases uniformly...
