Explanation:
parallel vectors have proportional direction ratios
Therefore 14/2=21/3=7/x
Solving for x we get x=1
Correct Question :
Vector A = 2i + 3j + xk and Vector B 14i + 21j +7k. If A and B Vector are parallel, then find the value of x.
AnsWer :
1.
Solution :
Let the,
Therefore,the value of x be 1.
