Find the foot of the perpendicular drawn...

Find the foot of the perpendicular drawn from the point `(2hat(i)-hat(j)+5hat(k))` to the line `vec(r)=(11hat(i)-2hat(j)-8hat(k))+t(10hat(i)-4hat(j)-11hat(k))`. Find also the length of the perpendicular.

Text Solution

Verified by Experts

The correct Answer is:
Hence, the required perpendicular distance is `sqrt(14)` units.
