Consider the following figure: (a) 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. (you should get g = 2GMr / (r^2 + a^2)^(3/2)) (b) Explain physically why the field should approach zero as r → 0. (c) Prove mathematically that the answer to part (a) behaves in this way. (d) Explain physically why the magnitude of the field should approach 2GM / r^2 as r → ∞. (e) Prove mathematically that the answer to part (a) behaves correctly in this limit.

Consider the following figure. An illustration shows two particles, each labeled M, one placed at each end of a vertical line. A horizontal line intersects the vertical line right at its center. A point P is at the right end of this horizontal line. The distance between the vertical line and the point P is r. The distance between the horizontal line and each particle M is a. (a) 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.) (b) Explain physically why the field should approach zero as r → 0. (c) Prove mathematically that the answer to part (a) behaves in this way. (d) Explain physically why the magnitude of the field should approach 2GM/r² as r → ∞. (e) Prove mathematically that the answer to part (a) behaves correctly in this limit.
