1994年高考物理试题第19题和1988年高考物理试题第二大题第8小题是一对孪生题,尽管从表面上看前者是电学题,后者是力学题,但是两题涉及的物理过程和分析思路如出一辙。本文对此作些对比和解析。
The 19th problem of the 1994 college entrance examination physics test and the 8th problem of the 1988 physics test physics test were the twin problems. Although the former is the electric problem and the latter is the mechanics problem, the two topics involve physics. The process and analytical ideas are exactly the same. This article makes some comparisons and analysis.
