Unformatted text preview: 4B Homework 08 *Question 1 A proton travels through uniform magnetic and electric fields. The magnetic field is in the negative x direction and has a magnitude of 2.72 mT. At one instant the velocity of the proton is in the positive y direction and has a magnitude of 1900 m/s. At that instant, what is the magnitude of the net force acting on the proton if the electric field is (a) in the positive z direction and has a magnitude of 5.86 V/m, (b) in the negative z direction and has a magnitude of 5.86 V/m, and (c) in the positive x direction and has a magnitude of 5.86 V/m? (a) Number 1.77E-18 Units N (b) Number 1.11E-19 Units N (c) Number 1.25E-18 Units N Answer a1: the number of significant digits is set to 3; the tolerance is +/-2% Answer b1: the number of significant digits is set to 3; the tolerance is +/-2% Answer c1: the number of significant digits is set to 3; the tolerance is +/-2% *Question 2 In Figure below, a charged particle moves into a region of uniform magnetic field , goes through half a circle, and then exits that region. The particle is either a proton or an electron (you must decide which). It spends 135 ns inthen exits that region....
