You have 4 submssions for each question. ubs: 2/4 iewing: Last esponse iew: All esponses otes pts 1 1/1 2 2/2 3/3 1. A proton moves at constant velocity in the +y direction, through a region in which there is an electric field and a magnetic field. The electric field is in the +x direction, and has magnitude 400 V/m. The magnetic field is in the -z direction, and has magnitude 0.85 T. What is the magnitude of the net force on the proton? F net = 0 [0] N What is the speed of the proton? v = 470.588 [471] m/s ubs: 3/4 iewing: Last esponse iew: All esponses otes pts 1 1/1 2 1/1 3 1/1 4 1/1 5 1/1 6 1/1 6/6 2. [MI02 20.RQ.05.alt01.] A copper wire with square cross section carries a conventional current I in the +z direction. There is a magnetic field B in the -y direction. Draw a diagram illustrating the situation, to help you answer the following questions. What is the direction of E parallel , the electric field that causes the current to flow? +z [ +z ] What is the direction of the drift velocity of the mobile electrons? -z [ -z ] What is the direction of the magnetic force on the moving electrons? +x [ +x ] What is the direction of E transverse , the electric field due to the Hall effect, inside the
