Question

if A 4i+3j-2k and B 8i+6j-4k then angel between them A and B is?​

Answer 1

Answer:

angel between A and B is zero.

Explanation:

given A .4i+3j-2k

if we multiply this with 2 then

(4i+3j-2k)*2=8i+6j-4k=B

we get B

so these vector are parallel to eachother.

so angel between A and B is zero.
