我们知道,各门科学中,物理与数学关系最亲,数学知识及方法是学习物理的重要工具,它提供了对物理问题进行数量分析和计算的方法,提供了物理概念与物理规律简捷精确的表达方式;同时它也是进行推理论证的有效工具和抽象手段.所以能熟练地运用数学处理物理问题,是学好物理的必要条件.题目:(2015年普通高等学校招生全国统一考试模拟试题)如图1所示,AB是半径为R的圆的一条直径,该圆处于匀强电场
We know that in all sciences, the relationship between physics and mathematics is the most relative. Mathematics knowledge and methods are important tools for studying physics. It provides methods for quantitative analysis and calculation of physical problems and provides simple and accurate physical concepts and physical rules It is also an effective tool and abstract means to carry on reasoning and argumentation.So it is a necessary condition to learn physics well to skillfully use mathematics to deal with the physics problem.Item Title (2015 National College Entrance Examination of the National Unified Examination simulated test) 1, AB is a diameter of a circle of radius R, which is at a uniform electric field
