Question
Consider two ions, labeled A and B. Each ion carries a positive charge q = +|c|. but they have different masses: MA and MB Both ions are accelerated until they have the same initial kinetic energy KE_0. then they are sent into a region containing a constant, uniform magnetic field of unknown magnitude and direction. The ions initial velocity is in the direct ion and they enter the B-field region at the origin. Within the field region, they follow curved paths confined to the xy-plane (Z = 0). then emerge at different locations on the y-axis ion A emerges at y = a. and ion B emerges at y = b. where b> a as shown What is the direction of the uniform magnetic field in the region x> 0? +xdirection (to the right) -x direction (to the left) +y direction (upward) +Z direction (out of the page) -Z direction (into the page) Given that the two tons have the same charge q. the same initial kinetic energy KE_0 and the trajectories shown in the figure, what can we conclude about their masses? mA > Ms mA
Explanation / Answer
13) e. -z direction (into the page)
14) c. We cannot conclude anything their masses from the given information.
