人类世工作组（AWG）成立于2009年，并于2016年得出结论，认为人类对地球造成的变化如此之大，以至于有必要建立一个新的地质时间单位。

Yeah, Coulomb's law gives the electrostatic force  as the Coulomb constant times charge 1 times charge 2 all divided by the square of the distance  between centers of charge all times unit vector r.

是的，库仑定律给出的静电力等于库仑常数乘以电荷 1 乘以电荷 2 除以电荷中心之间距离的平方乘以单位矢量 r。
