Mark the correct alternative in each of the following:
If lies in the plane of vectors
and
, then which of the following is correct?
Here, lies in the plane of vectors
and
, which means
,
and
are coplanar.
We know that is perpendicular to
and
.
Also dot product of two perpendicular vector is zero.
Since, ,
,
are coplanar,
is perpendicular to
.
So,
