The locus of a point which is equidistant from the points(-2,2,3), (3,4,5) is

The orthocentre of the triangle formed by the points(2,1,5), (3,2,3), (4,0,4) is

If (2,1,1) is the centroid of the triangle for which (3,2,-1), (2,-2,5) are two vertices then the third vertex is

If the orthocenter and the circumcentre of a triangle are (-3,5,1), (3,3,-1) then the circumcentre is

If (2,3,4) is the centroid of the tetrahedron for which (2,3,-1), (3,0,-2), (-1,4,3) are three vertices then the fourth vertex is
