1988年物理高考题中有这样一题: 两个球形行星A和B各有一卫星a和b,卫星的圆轨道接近各自行星的表面,如果两行星质量之比M_A/M_B=p,两行星半径之比R_A/R_B=q,则两卫星周期之比
The physics college entrance examination question in 1988 contained such a question: The two spherical planets A and B each have a satellite a and b. The satellite’s circular orbit approaches the surface of its own planet. If the ratio of the two planets’ masses M_A/M_B=p, the two planets’ radii The ratio R_A/R_B=q, the ratio of two satellite cycles
