Answer:
angle between vectors A & B would be Zero
Explanation:
vector A = 2i + 3j - k
vector B = 4i + 6j - 2k
=> vector B = 2 (2i + 3j - k)
Hence we can see they Both the vector Have just different magntude but same directions
so angle between vectors A & B would be Zero

Explanation:
Angle between two vectors can be determined by vector dot product and vector cross product.
Vector dot product is easier to do.
Hence option 4 is correct.
Hope it helps you.
