138249 Two objects are separated by a distance $R$. If one of the objects is replaced by another having the same mass and the separation distance is increased to $2 R$, then the initial gravitational force is

1 the same

138250 Three particles each of mass ' $m_{1}$ ' are placed at the corner of an equilateral triangle of side ' $\frac{L}{3}$ '. A particle of mass ' $m_{2}$ ' is placed at the midpoint of any one side of triangle. Due to the system of particles the force acting on ' $\mathrm{m}_{2}$ ' is $(\mathbf{G}=$ Universal constant of gravitation).
