Q. 225.0( 1 Vote )

Find the value of p, so that the lines and are perpendicular to each other. Also find the equations of a line passing through a point (3, 2, –4) and parallel to line l1.

Answer :

Given:


The equation of line can be rewritten as:



Vector form of L1:



Vector form of L2 :











P = 7 …(1)


Now let the line passing through point (3,2,-4) and parallel to L1 be L’.



(as L' is parallel to L1 and we can neglect the constant v


because it is deciding magnitude only.)
