As it is equilateral triangle so the distances of each charges from center are equal i.e $r$ (say)
Potential at center is $V = k (2 q / r - q / r - q / r) = 0$ .
Electric field is a vector quantity so the resultant field at the center will not be zero.

Three charges 2q,−q,−q are located at the vertices of an equilateral triangle. At the centre of the triangle :the field is zero but potential is nonzerothe field is nonzero but potential is zeroboth field and potential are zeroboth field and potential are nonzero

As it is equilateral triangle so the distances of each charges from center are equal i.e r (say) Potential at center is V=k(2q/r−q/r−q/r)=0.Electric field is a vector quantity so the resultant field at the center will not be zero.

Three charges $2 q, - q, - q$ are located at the vertices of an equilateral triangle. At the centre of the triangle :
the field is zero but potential is nonzero
the field is nonzero but potential is zero
both field and potential are zero
both field and potential are nonzero
