A vector A of magnitude 6 and another vector B have a resultant magnitude 12. The vector B: must have a magnitude of at least 6 but no more than 18

As,

a+b > r

b > r-a

b >12-6

b> 6

A vector A of magnitude 6 and another vector B have a resultant magnitude 12. The vector B:a. must have a magnitude of at least 6 but no more than 18b. may have a magnitude of 20c. cannot have a magnitude greater than 12d. must be perpendicular to A
