Hi
Please have a look on the attachment and kindly help me with the query, Q1, there.
Q2: I understand that coplanar vectors are those which exist on the same same plane. The unit vectors i, j, and k are non-coplanar vectors and are perpendicular to each other (in other words the planes in which they exists are at 90 degrees to each other). Is it necessary for non-coplanar vectors to be be perpendicular to each other.
Thank you for the help.
Regards
PG
