Two vectors are given by vec(A) = hat(i)...

Two vectors are given by `vec(A) = hat(i) + 2hat(j) + 2hat(k)` and `vec(B) = 3hat(i) + 6hat(j) + 2hat(k)`. Another vector `vec(C )` has the same magnitude as `vec(B)` but has the same direction as `vec(A)`. Then which of the following vectors represents `vec(C )` ?

A

`(7)/(3) (hati+2hatj+2hatk)`

B

`(3)/(7) (hati-2hatj+2hatk)`

C

`(7)/(9) (hati+2hatj+2hatk)`

D

`(9)/(7) (hati+2hatj+2hatk)`
