Question

If a is a collinear vector with b=3^i+6^j+6^k
and a.b=27. Then, a is


Your Answer
A
3(^i+^j+^k)
Your Answer
B
2(^i+^j+^k)
Correct Answer
C
^i+2^j+2^k
Your Answer
D
2^i+3^j+3^k

Solution

The correct option is C ^i+2^j+2^k
As a is collinear to b 
So,
a=λba.b=λb.b=279λ+36λ+36λ=27λ=13a=^i+2^j+2^k
