Question

Let a and b be nonzero vectors with compb a = 0. What can you conclude about a and b? Explain. (Note: b is the subscript for comp.)

Answer 1

Draw a diagram of these two vectors. What does that diagram look like?

Answer 2

if a.b=0 means dot product 0, hence they must b perpendicular
cox a.bcos(x)

where x =angle between a and b, in this case it wud b 90

Answer 3

i hope i read the question correctly
