A prоtоn mоves with constаnt velocity v to the left through а region where there is а uniform magnetic field of magnitude B that points into the page. There is also an electric field in this region (the electric field or force cancels the magnetic force, thus the proton moves straight as shown). The magnetic field and electric field are produced by devices not shown on the diagram. Choose from the following possible directions to answer the questions below: What is the direction (a-g) of the electric field in this region? xx.png Q9.png
