Question

请帮我先翻译再解答一下这道物理题，谢谢

Express the unit and dimension for the electric field in terms of unit and dimensionality of charges, if we take the permittivity of the empty space as dimensionless quantity.
Express the charge dimension in terms ofmechanical fundamental quantities: L,M,T

Answer 1

我们是通过电的单位和量纲来表示电场的单位和量纲的，如果我们把真空的电容率定义为无量纲的量，请用基本力学量米、千克、秒来表示电荷的量纲。
答案：q的量纲=L^(1/2)M^(1/2)

Answer 2

用单位和尺寸表达了电场的单位和维度的费用,如果我们把介电常数的空无量纲为数量。
负责在表达分解的机械产品概念设计尺寸、基本的数量,
