高中物理题,不只在物理基础上考查学生,在数学知识的应用能力上也有很高的要求,如果不能很好地联系数学知识的实际应用或对应用知识掌握不全面,在物理解题时就会出现纰漏。下面来看一道数理联系密切的题目,以及从该问题中衍生出来的注意事项。如图,在坐标系x Oy的第一象限中有一个沿y轴的匀强电场,电场强度为E,在二三四象限中则存在同强度的匀强磁场,磁
The high school physics question not only examines students on the basis of physics, but also has high requirements in the application of mathematical knowledge. If the application of mathematical knowledge cannot be well connected or the application knowledge is not comprehensively grasped, There will be flaws. Let’s take a look at the topics that are closely related to mathematics and the issues that arise from this issue. As shown in the figure, in the first quadrant of the coordinate system x Oy, there is a uniform electric field along the y-axis, the electric field strength is E, and in the two-fourth quadrant there is a uniform magnetic field of the same intensity, magnetic
