Find the position vector of centroid of ...

Find the position vector of centroid of a triangle having position vector of its vertices as `2hati+3hatj-4hatk` , `-2hati+3hatj+4hatk` and `-6hatj`

Text Solution

Verified by Experts

The position vector of centroid `=(veca+vecb+vecc)/(3)`
`=((2hati+3hatj-4hatk)+(-2hati+3hatj+4hatk)+(-6hatj))/(3)=vec0`(Null vector)
