1.if the centroid of a triangle abc is the origin, point b and c are respectively ( 0,6,0 ) and ( 0,0,6 ) then the point a is a. ( 0,-6,0) b. ( 0,0,-6) c. ( 0,6,6,) d. ( 0,-6,-6)
2. the ratio in which the line joining the points ( a, b,c ) and ( -a,-c,-b ) is divided by the xy plane is :
a. a: b
b. b: c
c. c: a
d. c: b
