The points A and B have position vectors, relative to the origin O, given by OA= {-1,3,5} and OB= {3,-1,-4}. The line l passes through A and is parallel to OB. THe point N is the foot of the perpendicular from B to l.

--Find the position vector of N and find the length of BN

-- Find the equation of the plane containing A,B,N
