If hat(i)+2hat(j)+3hat(k)and2hat(i)-hat(j)+4hat(k) are the position vectors of the points A and B, then the position vector of the points of trisection of AB are

Answer»

`(4)/(3)hat(i)+hat(J)+(10)/(3)hat(k),(5)/(3)hat(i)+(11)/(3)hat(k)`
`-(4)/(3)hat(i)-hat(j)-(10)/(3)hat(k),-(5)/(3)hat(i)-(11)/(3)hat(k)`
`(4)/(3)hat(i)-hat(j)-(10)/(3)hat(k),(-5)/(3)hat(i)+(11)/(3)hat(k)`
`-(4)/(3)hat(i)+hat(j)-(10)/(3)hatk,(5)/(3)hat(i)-(11)/(3)hat(k)`
