Find the distance of the point (- 1, - 5,- 10) from the point of intersection of the line r=2^i−^j+2^k+λ(3^i+4^j+2^k) and the plane r.(^i−^j+^k)=5
A line passing through the point A with position vector a= 4i+ 2j+2k is parallel to the vector b = 2i+3j+6k . Find the length of the perpendicular drawn on this line from a point P with position vector r= i + 2 j+ 3k
