Question

Consider the following figure.

This answer has not been graded yet.

magnitude g = direction ---Select---towards the center of massaway from the center of mass Compute the vector gravitational field at a point P on the perpendicular bisector of the line joining two objects of equal mass separated by a distance 2a as shown in the figure above. (Use any variable or symbol stated above along with the following as necessary: G for the gravitational constant.) Explain physically why the field should approach zero as r ? 0. Prove mathematically that the answer to part (a) behaves in this way. (Do this on paper. Your instructor may ask you to turn in this work.) Explain physically why the magnitude of the field should approach 2GM/r2 as r ? ?.

Explanation / Answer

. Since mass 1 exerts a force of

We know the y components are equal and opposite and that both x components are pulling at Point P in the
