Question

As shown in the figure below, a charged particle (mass = 3.54 x 10-25kg) is accelerated from rest from initial (105V) to final (0 V) voltage as shown. The particle then enters a region of uniform magnetic field with magnitude 1.54 T. If the magnitude of the particle's charge is 1.6x10-19 C, what is the distance, d, shown in the figure? Assume that any losses of the particle's energy are negligible. Write your answer to three significant figures. You will report your units in Question 2, and Question 3 will go through the scenarios for the sign of the charge and the direction of the magnetic field.

For the scenario above, choose all the possible combinations of the sign of the particle charge and the direction of the uniform magnetic field that is consistent with the picture shown. (Hint: you will have to consider both parts of the problem, the acceleration of the charge and the motion in the magnetic field.)
