2014年江苏高考物理第14题是一道关于带电粒子在有界磁场中运动的计算题,通过调整带电粒子的速度大小,使带电粒子到达不同地方.其实该题与曾经出现过的一道考试题有相似的背景和解题方法,当然在磁场方向设置和带电粒子入射位置方面有所不同.下面就这二题解题作一比较.1(原题).如图1所示,L1和L2为两平行线,L1上方和L2下方都有垂直纸面向里的磁感应强度相同的匀
2014 Jiangsu Physics Entrance Examination Question 14 is a calculation of charged particles moving in a bounded magnetic field, by adjusting the speed of charged particles to the charged particles to reach different places. In fact, the question and there has been a test questions A similar background and solution method, of course, in the magnetic field direction and charged particle entrance position is different. The following questions on these two questions for a comparison .1 (original title.) As shown in Figure 1, L1 and L2 are Two parallel lines, L1 above and below L2 have vertical paper-oriented magnetic induction of the same intensity
