7 Find the vector product axb. If a = 2i + 3j + 4k and b = 5i - 2j + k
11i + 18j - 19k
2j + 3k
5i - 6j + 7k
4i - 6j +11k

9 The centroid of a triangle of the triangle OAB is denoted by G. If o is the origin and line(OA) = 4i + 3j, line(OB) = 6i - j,find line(OG) in terms of the unit vectors I and j
10i - 3j

12(10i−2j)
10i + 2j

13(10i+2j)
10 Given that a = 5i +2j - k and b = I - 3j + k. Find (a + b) x (a + b).
2i - 12j - 34k
2i + 12j + 34k
2i -3j + 12j
2i + 2k
