## JUNIOR INTER MATHS ALGEBRA VECTORS

1. Find the unit vector in the direction of the vectors a = 2i + 2j – 5k and b = 2i + j + 3k.

2. Find the unit vecot in the direction of vector a = 2i + 3j + k.

5. Show that the points whose position vectors are  – 2a + 3b + 5c, a + 2b + 3c, 7a – c are collinear when a, b, c are coplanar vectors.

7. if OA = i + j + k, AB = 3i – 2j + k, BC = i + 2i – 2k and CD = 2i + j + 3k then find the vector OD

8. Let a = 2i + 4j – 5k, b = i + j + k and c = j + 2k. Find the unit vector in the opposite direction of a + b + c.
