= 3î - 2) - 4k. 1. A vector A has a magnitude of 5 units and it has a direction along a vector B = 3i Write down the vector A in terms of the unit vectors. [Marks 5] 2. Find out the projection of vector A =- 31+ 2) + 3k on B = 21+ 3) + Akif A-2B. [Marks 10] 2i 3. Calculate the area formed by the two vectors A = 31 + 2) + 4k and B 21 - 2) + k. Also find out the angles that the direction of area makes with the X, Y and Z axes. [Marks 12]
