Let ABC be a triangle having its centroid its centroid at G. If S is any point in the plane of the triangle, then `vec(SA) + vec(SB)+vec(SC)=`

A

SG

B

2SG

C

3SG

D

0

Text Solution

Verified by Experts

The correct Answer is:
C
We have, `SA+SB+SC=SA+(SB+SC)`
`implies SA+SB+SC=SA+2SD`
= (1+2) SG = 3SG
