A `3kg` mass and `4kg` mass are placed on `X` and `Y` axes at a distance of `1` meter from the origin and a `1kg` mass is placed at the origin. Then the resultant gravitational force on `1kg` mass is

Two objects of masses 4kg and 3kg are placed along X and Y axes respectively at a distance of 1m from the origin. An object of mass 1kg is kept at the origin of the co-ordinate system. Calculate the resultant gravitational force attraction on the object at the origin.
