Consider the line l : vecr= hati- hatj+ ...

Consider the line `l : vecr= hati- hatj+ hatk+ t(2 hati+3 hatj-6 hatk)` and the plane `p:vecr.(2 hati+3 hatj-6 hatk)=7`.
Statement -I : Then line `l` and the plane 'p' meet in a unique point .
Statement -II: The line `l` is at right angoles to the plane 'p'

Statement - I is True, Statement - II is True , Statement - II is a correct explanation for Statement - O

Statement- I is True, Statement -II is True , Statement - II is not a correct explanation for Statement - I

Statement - I is True, Statement - II is False.

The angle between the line vecr=( hati+2 hatj- hatk)+ lambda( hati- hatj+ hatk) and the plane vecr. (2 hati- hatj+ hatk)=4 is __

`"cos"^(-1) (1)/(3)`

`"cos"^(-1) (1)/(sqrt3)`

`"sin"^(-1) (1)/(3)`

`vecA and vecB` are perpendicular

`vecA xxvecB=vecBxxvecA`

`vecA and vecB` have the same magnitude

`vecA*vecB=0`
