Vector A is 3 m long and vector B is 4 m long. The length
ofthe sum of the vectors must be:
A. 5 m
B. 7 m
C. 12 m
D. some value from 1 m to 7 m.

Respuesta :

Answer:d

Explanation:

Given

Magnitude of Vector A is 3 m

and Magnitude of vector B is 4 m

So the maximum value of resultant can be 7 m when both are at an angle of [tex]0^{\circ}[/tex]

and its minimum value can be 1 m when both are at angle of [tex]180 ^{\circ}[/tex]

So the resultant must lie between 1 m to 7 m
