It would be 120^01200

Explanation:

Given the forces are equal, it would be reasonable to assume they have the same angle between them as in the diagram below:

If we then consider components of forces in the x direction:

F_2cos 30^0-F_1cos90^0-F_3cos30^0F2cos300F1cos900F3cos300
=>F_2cos 30^0-F_3cos30^0F2cos300F3cos300

Since F_1=F_2=F_3F1=F2=F3 then the above equates to nil

Similarly in the y direction:

F_1 -F_2sin 30^0-F_3sin30^0F1F2sin300F3sin300
=>F_1-0.5*F_2-0.5*F_3=0F10.5F20.5F3=0

Hence no resultant force
