Let alpha = (lambda-2) a ne b and beta =...

Let `alpha = (lambda-2) a ne b` and `beta =(4lambda -2)a + 3b` be two given vectors where vectors a and b are non-collinear. The value of `lambda` for which vectors `alpha` and `beta` are collinear, is.

Text Solution

Verified by Experts

The correct Answer is:
4
`vecbeta=k vec alpha`
`therefore (4lambda-2)/(lambda-2)=(3)/(1)`
`4lambda-2=3lambda-6`
`lambda=-4`
