AD is the median of a\[\Delta ABC,\]and O is the centroid such that \[AO=10\,\,cm\] The length of OD (in cm) is [SSC (FC1) 2012] |
A) 4
B) 5
C) 6
D) 8
Correct Answer: B
Solution :
Point O is the centroid and we know that centroid divides the median in ratio 2:1. |
\[\therefore \] \[OD=\frac{AO}{2}=\frac{10}{2}\] |
\[\therefore \] \[OD=5\,\,cm\] |
