Consider an infinite distribution of point masses (each of mass m) placed on x-axis as shown in the diagram. What is the gravitational force acting on the point mass placed at the origin ?

Three identical point mass each of mass 1kg lie in the x-y plane at point (0,0), (0,0.2m) and (0.2m, 0). The net gravitational force on the mass at the origin is

Three point masses m,m and 2m are placed on the vertex of an equilateral triangle of side 'a' Another point mass 'm' is placed at the centroid of the triangle as shown in the figure. If the magnitude of net force on the point mass placed at centroid is (KGm^2)/(a^2) then find the value of K (G= universal gravitational constant )

We know that when two equal masses are placed on a line then, gravitational force on a third mass is zero due to these two masses when the third is placed at the centre of line joining the two masses. But if third mass is placed anywhere else on the x-axis, the gravitational force acts on that mass due to these two masses. Consider a system shown in figure. In this system two point masses of mass M each are placed at y-axis at a distance a from origin and these masses are fixed. If a third point mass of mass m is released at a distance x from origin on x-axis, then answer the following questions. Which of the following graphs best represents the variation of force on mass m with distance x ?
