This is a vector addition question.As each of the particle is exering an repulsive force on each other of magnitude F.
As the triangle given is an equilateral triangle. Hence the angle between the two forces is 60 degrees.
 
So net force = \sqrt{F^{2}+F^{2}+2F^{2}cos(60)}
Hence the answer is third opption\sqrt{3}F

As the charges are same. So they will repel each other. 
Here the triangle is equilateral. So the angle made will be 60 degree. 
Hence net force=√f2+f2+2×f×fcos60
=√2f2+2f2×1/2
=√3f2
=√3×f 
 
Hence root 3×f is the answer.
