选这题的原因就是解释一下上面的几个性质 首先,整个导体电势相同,所以说表面是个等势面 其次,电荷分布在它表面 同时,因为表面是等势面,所以说电场方向垂直(也就是选出C的理由) 左边那个小球曲率更大,那它表面聚集的电荷更多(怎么判断曲率,大家可以看它的R,R越小,曲率越大) 曲率--curvature 电势能 单看计算...
Powerful physics problem solvers also frequently use a type of free association. By learning to associate small hints with a corresponding physics principle, they can often visualize an equation for a problem even before they have fully read it. Again it's a skill that can be learned. ...
PHYSICS C: ELECTRICITY AND MAGNETISM SECTION II Time—45 minutes 3 Questions Directions: Answer all three questions. The suggested time is about 15 minutes for answering each of the questions, which are worth 15 points each. The parts within a question may not have equal weight. Show al...
WEBBER ET AL.: CRYSTALLIZATION OF PEGMATITES712The conduction equation for a sheet of thickness 2a(Jaeger1968) assuming the same thermal diffusivity,κ, for both magmaand country rock is the following:T/T0=12erfx/a+12κt/a2−erfx/a−12κt/a2...
