Question

For which values of A and B 2i-3j-k and ai+bJ-2k vectors can be parallel​

Answer 1

Answer:

Using your question,  a=(2,3,−1)  and  b=(4,6,2) , you will get three simultaneous equations

Explanation:

a1/a2 = b1/b2 = c1/c2

therefore

2/a = 3/b = 1/2

so,

2/a=1/2

a = 4

and,

3/b=1/2

b=6

HENCE ai+bj-2k = 4i+6j-2k
