p का मान ज्ञात कीजिए ताकि रेखाएँ `( 1- x )/(3) = ( 7y - 14)/( 2p ) = (z - 3)/( 2 )` और `( 7 - 7x )/( 3p ) = ( y - 5) /(1) = ( 6- z)/(5)` परस्पर लंब हो |

Fiind m, if the lines (1-x)/(3)= ( 7y-14)/(2m ) = (z-3) /(2) and ( 7-7x)/(3m) = (y-5)/(1) = (6-z)/(5) are at right angles.

If the lines (1 -x )/(3) = ( 7y - 14)/(2 lamda) = (z - 3)/(2) "and" (7 - 7x)/(3lamda) = (y - 5)/(1) = ( 6 - z ) /(5) are at right angle, then the value of lamda is

The value of p so that the lines (1-x)/(3) = (7y - 14)/(2p) = (z -3)/(2) and (7-7 x)/(3p) = (y-5)/(1) = (6 -z)/(5) are at right angles are

Find the value of p, so that the lines (1 -x)/(3) = ( 7y - 14)/(2p) = ( z -3)/( 2) and ( 7-7x)/(3p) = ( y-5)/(1) = ( 6 - z)/(5) are intersect each other are right angle.

(i) Find the value of 'p' so that the lines : l_(1) : (1 - x)/(3) = (7y -14)/(2p) = (z - 3)/(2) and l_(2) : (7 -7x)/(3p) = (y - 5)/(1) = (6 - z)/(5) are at right angles. Also, find the equations of the line passing through (3,2, -4) and parallel to line l_(1) . (ii) Find 'k' so that the lines : (x - 3)/(2) = (y + 1)/(3 ) = (z - 2)/(2k) and (x + 2)/(1) = (4 -y)/(k) = (z + 5)/(1) are perpendicular to each other.

Find the value of p so that the lines (1-x)/(3)= (7y-14)/(2p)= (z-3)/(2) and (7-7x)/(3p)= (y-5)/(1)= (6-z)/(5) are at right angles
