應用萬有引力定律,在地面mg=GMm/R²,而在高樓頂端mg'=GMm/(R+h)²,這兩個式子聯立

題目：

應用萬有引力定律,在地面mg=GMm/R²,而在高樓頂端mg'=GMm/(R+h)²,這兩個式子聯立就可以求出樓的高度,式子中m代表氣壓計的質量,M代表地球質量,G是萬有引力常量,R代表地球的半徑,h就是高樓的高度.
翻譯以上一段 謝絕翻譯機 好的話會加分

解答：

Applicating the law of gravity,on the ground is "mg = GMm / R ² " while on the top of high building is "mg '= GMm / (R + h) ²".Combining these two formulas together will calculate the height of the building.In these two formulas,m representes the mass of barometric pressure ,M representes Earth's mass,G is the gravitational constant,R means the radius of the Earth,h is the height of the high building.
一句一句的打上去的,稍微有點英語底子的就知道不是機器翻譯的,除了幾個專業名詞不太確定,估計正確率在百分之八十五以上.
