本文结合2012年和2013年北京市高考理综卷第24题的命题内容及考试情况,管窥北京市高考物理压轴题的试题特色以及能力考查的方式转变.1 2012年北京市理综卷第24题1.1试题内容图1匀强电场的方向沿x轴正向,电场强度E随x的分布如图1所示,图中E0和d均为已知量.将带正电的质点A在O点由静止释放.A离开电场足够远后,再将另一带正电的质点B放在O点也由静止释放.当B在电场中
This article combines the 2012 and 2013 Beijing college entrance examination volume 24 of the proposition content and examination of the case, the Beijing college entrance examination physics finale test questions feature and ability to examine the changes in the way.1 2012 Beijing Science Volume 24 Problem 1.1 The contents of the test questions Figure 1 Direction of the uniform electric field along the positive x-axis, the distribution of the electric field strength E with x shown in Figure 1, E0 and d are known quantities in the figure will be positively charged particle A in O The point is released from rest .A far enough away from the electric field, then another positive particle B is also released by static release point O. When B in the electric field
