If a,b and c are non-coplanar vectors and `lamda` is a real number, then the vectors `a+2b+3c,lamdab+muc and (2lamda-1)c` are coplanar when

A

`mu in R`

B

`lamda=(1)/(2)`

C

`lamda=0`

D

no value of `lamda`

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
For coplanar vectors `|(1,2,3),(0,lamda,mu),(0,0,2lamda-1)|=0`
or `(2lamda-1)lamda=0` or `lamda=0,(1)/(2)`.
