Q4 of 51 Page 26

Show that each of the following triads of vectors is coplanar :

Formula : -





Given: -



we know that three vector are coplanar if their scalar triple product is zero



we have



now, using



= – 4(12 + 13) + 6( – 3 + 24) – 2(1 + 32)


= 0


hence, the Given vector are coplanar.
