\underline{30} Berdasarkan Rajah 8, titik P berada pada jarak r dari jasad berjisim M di titik X dan jarak 2 r dari jasad berjisim M di titik Y.
Based on Diagram 8, the point P is at a distance of r from an object with mass, M at X, and distance 2 r from an object with mass, M at Y.
Rajah 1
Diagram 1
Kesemua yang berikut akan berlaku pada objek yang diletakkan di P kecuali
All the following will happen to an object placed at P except
A Bergerak ke X
Move to X
B Ditarik oleh objek di X
Pulled by object at X
C Ditarik oleh objek di Y
Pulled by object at Y
D Kekal pegun
Remain stationary
We know both X and Y exert âgravitational pullâ on object P, therefore B and C will happen.
Based on Newtonâs Law of Gravitation where,
Since X and Y both have the same mass, and M is at a closer distance to P, assuming that X is huge enough for âpullingâ to happen, the ânet effectâ of P will be moving towards X.
Therefore, by elimination, D is the exception and hence is the answer, unless there is an additional force resisting the ânet pullingâ of P to M, which is unlikely considering the absence of information on such force.
