Let the position vectors of A and B be 3...

Let the position vectors of A and B be `3hat(i)-hat(j)+hat(k)` and `-hat(i)+2hat(j)+3hat(k)`. Find the vector `vec(AB)` and its magnitude Also, determine the unit vector in the direction of `vec(AB)`.

Text Solution

Verified by Experts

The correct Answer is:
`vec(AB)=-4hat(i)+3hat(j)+2hat(k)|vec(AB)|=sqrt(29),` Unit vector `=(-4)/(sqrt(29))hat(i)+(3)/(sqrt(29))hat(j)+(2)/(sqrt(29))hat(k)`
