A vector 
has components 2p and 1 with respect to a rectangular cartesian system. This system is rotated through a certain angle about the origin in the counter clockwise sense. If, with respect to the new system, has component p + 1 and 1, then
has components 2p and 1 with respect to a rectangular cartesian system. This system is rotated through a certain angle about the origin in the counter clockwise sense. If, with respect to the new system, has component p + 1 and 1, then- p ≠ 0
- p = 1 or
- p = –1 or
- p = 1 or p = –1
- none of these
Answer
(D) p = 1 or p = –1
