Asked by The orange baboon

The position vector of the points A,B and C are respectively: a=2i ̂-3j ̂+k ̂,b=4i ̂+2j ̂+5k ̂ and c=3i ̂-2j ̂+2k ̂. Find the position vector: (i) P_AB (ii) P_BC (iii) P_CA?

If you mean P_AB is the vector from A to B, then that is just
b-a = 2i+5j+4k

do the others in like wise
