At what distance from this particle does its electric field have a magnitude of 11.6 ? ANSWER: m Problem 21.39 Description: (a) An electron is moving east in a uniform electric field of magnitude E directed to the west. At point A, the velocity of the electron is v_1 pointed toward the east. What is the speed of the electron when it reaches point B, which is a distance. .. Part A An electron is moving east in a uniform electric field of magnitude 1.47 directed to the west. At point A , the velocity of the electron is 4.55 × 10 5 pointed toward the east. What is the speed of the electron when it reaches point B , which is a distance of 0.400 east of point A ? Use 1.60 × 10 19 for the magnitude of the charge on an electron and 9.11 × 10 31 for the mass of an electron. ANSWER: m/s Part B A proton is moving in the uniform electric field of part (a). At point A , the velocity of the proton is 1.87 × 10 4 , again pointed towards the east. What is the speed of the proton at point B ? Use 1.67 × 10 27 for the mass of a proton.
