Q. if `(2,-1,2)` is the centroid of tetrahedron `OABC` and `G_1` is the centroid of `Delta ABC` then `|barOG_1|=`

A=(1,-1,2),G=(3,1,1) are one vertex and centroid of tetrahedron ABCD and G_1 ,is the centroid of DeltaBCD then AG_(1)=

A=(1,-1,2),G=(3,1,1) are one vertex and centroid of tetrahedron ABCD and G_(1) is the centroid of /_BCD then AG_(1)=

In the tetrahedron ABCD, A=(1,2,-3) and G(-3,4,5) is the centroid of the tetrahedron. If P is the centroid of the Delta BCD then AP=

In the tetrahedrom ABCD, A=(1,2,-3) and G=(-3,4,5) is cntroid of tetrahedron. If P is the centroid of triangle BCD then AP=

If G is the centroid of Delta ABC and AG-BC, then /_BGC is :

If G is the centroid of Delta ABC, G' is the centroid of Delta A' B' C' then vec(A)A' + vec(B)B' + vec(C)C' =

If G is the centroid of Delta ABC and G' is the centroid of Delta A' B' C' " then " vec(A A)' + vec(B B)' + vec(C C)' =

If G is the centroid of Delta ABC and G' is the centroid of Delta A' B' C' " then " vec(A A)' + vec(B B)' + vec(C C)' =

If G is the centroid of Delta ABC and G' is the centroid of Delta A' B' C' " then " vec(A A)' + vec(B B)' + vec(C C)' =
