A) \[\left( \frac{a}{3},\frac{b}{3},\frac{c}{3} \right)\]
B) \[\left( \frac{3}{a},\frac{3}{b},\frac{3}{c} \right)\]
C) \[\left( \frac{1}{a},\frac{1}{b},\frac{1}{c} \right)\]
D) \[(a,b,c)\]
Correct Answer: D
Solution :
Obviously, co-ordinates of A, B, C are respectively \[(3a,\,\,0,\,\,0),\] \[(0,\,\,3b,\,\,0)\] and \[(0,\,\,0,\,\,3c).\] Hence centroid is \[(a,\,\,b,\,\,c).\]You need to login to perform this action.
