If the line 
= 
= 
and 
= 
= 
intersect, then k is equal to :
A
– 1
B
C
D
0
Text Solution
Verified by ExpertsThe correct answer is:
C
= 
= 
= 
= 
(1, – 1, 1) ; 
= 
(2, 3, 4)
(3, k, 0); 
= 
(1, 2, 1)
These lines will intersect if lines are coplaner
, 
& 
are coplaner
∴ 
= 0
= 0
⇒ 2(–5) – (k + 1) (– 2) – 1 = 0
⇒ 2(k + 1) = 11
⇒ k =
