Let the foot of the perpendicular of P(2,−3,1) on the line
x+12=y−33=z−2−1 be Q.
If direction ratios of the line segment joining P and Q be l,m,n, then which of the following relations are correct ?
2l+3m−n=0
Let Q be the foot of the perpendicular P. PQ will be perpendicular to the given line. If two line segments with direction ratios (a,b,c) and (u,v,w) are perpendicular, then
au+bv+cw=0
Direction ratios of PQ is given as l,m,n and the line segment has direction ratios 2,3,−1
⇒2l+3m−n=0
