Two spheres A and B of equal radii R, each are uniformly dense with densities `2 rho` and rho respectively are placed as shown in figure.The initial acceleration of particle placed at point P due to gravity of both the spheres will be (P is just above the surface of sphere B).

Options

A. `(8π/27)rho GR`
B. `(4π/3)rho GR`
C. `(28/27)π rhoGR`
D. `(4π/27)rho GR`
