Four point positive charges are held at the vertices of a square in a horizontal plane. Their masses are 1kg,2kg,3kg,&4kg. Another point positive charge of mass 10kg is kept on the axis of the sqaure. The weight of their fifth charge is balanced by the electrostatic force due to those four charges. If the four charge on the vertices are released such that they can freely move in any direction(vertical, horizontal etc.) then the acceleration of the centres of mass of the four charges immediately after the release is (Use g=10 m/s2)
