p3 O/N 2007
10.) The straight line l has equation r = i + 6j − 3k + s(i − 2j + 2k). The plane p has equation
(r − 3i).(2i − 3j + 6k) = 0. The line l intersects the plane p at the point A.
(i) Find the position vector of A.
(ii) Find the acute angle between l and p.
(iii) Find a vector equation for the line which lies in p, passes through A and is perpendicular to l.
I could solve (i) and (ii) but got stuck with (iii), somebody help me out, exams knocking the door, need the answer as soon as possible
(by tomorrow if possible)
In Addition:
If Possible please send some notes on
