Two vectors 
and 
add up to a vector 
When vector 
is made 3 times as long and vector 
is doubled in length, without changing their directions, then it is found that vector 
is also doubled in length, without change in direction. Then which of the following is true [J & K CET 2012]
and add up to a vector When vector is made 3 times as long and vector is doubled in length, without changing their directions, then it is found that vector is also doubled in length, without change in direction. Then which of the following is true [J & K CET 2012] - All three vectors must be parallel
and 
must be parallel to each other, but need not be parallel to and 
and 
must be perpendicular to each other- It is impossible for three non-zero vectors
and 
to have the property stated above
Answer
(D) It is impossible for three non-zero vectors and to have the property stated above
