G = 2000+600 = 2600 Newton
The supporting force of object A is provided by the pressure between A and B, and between A and C. This pressure can be decomposed into two forces, namely, horizontal force and vertical force, in which the upward vertical force provides upward supporting force, and the two horizontal forces are in opposite directions and cancel each other out.
The angle between the two sides is 30, so the angle between one side and the vertical is 15.
Available: 2f× sin 15 = g = 2600n.
So: F=6954.67N
