Question

find the position vectors of the points which trisect the line joining the points whose position vectors are i+2j+7k and 3i+j-k

Answer 1

Explanation:

you should have to find two position vectors between the given positional vectors . to find the first position vector take the ratio 1:2 internally and for the second positon vector take the ratio 2:1 as it is trisected

using the position vector formula we get the respective answer's
