The plane `vecr cdot vecn = q` will cotain the line `vecr = veca + lambda vecb` if

`vecb.vecn""ne0,veca.vecn""neq`

`vecb.vecn=0,veca.vecn""neq`

`vecb.vecn=0,veca.vecn=q`

`vecb.vecn""ne0,veca.vecn=q`

Text Solution

Verified by Experts

The correct Answer is:

We must have `vecb.vecn=0andveca.vecn=q.`
