答
楼上的,你看过中子星?计算过程完全粘贴别人的,翻译得好外行,是求“在行星表面的重力加速度”而不是“加速度”
答
翻译:一个太空人着陆再一个直径为1200km质量为1.23x10^34kg小行星。求他的加速度。
g = GM/r^2 = 6.67×10^(-11)N•m^2/kg^2 ×1.23x10^34kg / (6 ×10^5)^2
= 2.279*10^12 M/S^2
楼上的,哪里会吓人,没看过那些什么中子星吗?
答
g = GM/r^2 = 6.67×10^(-11)N•m^2/kg^2 * 1.23x10^34kg / (6 * 10^5)^2
= 2.279*10^12 M/S^2
吓人吧.
这个星体的密度比地球大10^10倍...
答
先翻译过来啊?
