SAT备考 - 每日一题（58）方程式

[58]这道题是必考题型，归为isolating quantities problems，就是将方程中的某个变量提取出来/孤立出来。 F = Gm1m2/d^2 The equation above shows the F, the gravitational force between two objects, in terms of G, the gravitational constant, m1 and m2, the masses of the two objects, and d, the distance between the two objects. Which of the following correctly expresses d in terms of F, G, m1 and m2? 上述方程中，F代表两个物体之间的重力作用力，G是万有引力常数，m1和m2分别代表两个物体的质量，d是两个物体之间的距离。那么，以下哪个等式正确地使用了F、G、m1和m2表达d？
