论文部分内容阅读
第一部分注意事项: (1) 凡是题目的下面标有“答案:____”者,请把答案填写在其中横线上空白处,不要求写出演算过程。 (2) 以下是一些物理恒量和数据,解题时如有需要可选用。万有引力恒量 G=6.67×10~(-11)牛顿·米~2千克~(-2)。地球半径 R=6.4×10~6米。静电力恒量 k=9.O×10~9牛顿·米~2·库仑~(-2)。基本电荷 e=1.60×10~(-19)库仑。
The first part pays attention to: (1) If all the questions are marked with “Answer:____” below, please fill in the blanks on the horizontal lines and do not ask for the calculation process. (2) The following are some physical constants and data, which can be used if necessary to solve problems. Universal gravitational constant G = 6.67 × 10 ~ (-11) Newton · m ~ 2 kg ~ (-2). The radius of the Earth R=6.4×10~6 meters. The electrostatic force constant k=9.O×10~9 Newton·m~2·Coulomb~(-2). The basic charge e=1.60×10-19 coulombs.
