Question
Two vectors started from the origin and moved to the east and north direction 5 m, 7 m, respectively, and the angle between the vectors is 90 degrees, then find the resultant of the vectors.
- 2
- 1.3
- 1.5
- 8.6
Hint:
If two vectors A and B with magnitude a and b respectively are given and the angle between them is θ Then the magnitude of the Resultant of A and B is R = 
The correct answer is: 8.6
- If two vectors A and B with magnitude a and b respectively are given and the angle between them is θ Then the magnitude of the Resultant of A and B is R =
- R =
- R = 8.6
- If two vectors A and B with magnitude a and b respectively are given and the angle between them is θ Then the magnitude of the Resultant of A and B is R =
- R =
- R = 8.6
