Dua buah benda bermassa M dan 3M berada pada jarak a satu sama lain. Tentukan percepatan gravitasi di suatu titik P yang terletak di antara kedua benda dan berjarak 1/3 a dari benda bermassa M! (PAKE CARA)

DewiLissy Gambar dulu arah percepatannya..pada titik p, arah percepatan oleh benda M ke kiri, oleh 3M ke kanan, jd berlawanan arah.percepatannya: g = g1-g2 = G.M/(1/3a)²-G.3M/(2/3a)² = G.M/1/9a²-3GM/4/9a² =9GM/a²-27/4 GM/a² = 36/4 GM/a²-27/4 GM/a² = 9 GM/a²
