Question

the resultant of two force 5N and 10N is never be
A. 12N
B. 5N
C. 10N
D. 4N
(Explain with diagrams)

Answer 1

Ans is 4N. The range of resultant of 2 vectors A B is from A+B TO A-B. All values coming in between this range is possible.

Answer 2

Answer:

The magnitude of the resultant R of two forces of magnitudes 5N and 10N, can be any thing between,

| 5N - 10N| ≤ R ≤ |5N + 10N|

The force is a vector its actual magnitude and direction will depend on the directions in which these forces are acting is required, at the least we need to the angle between these forces, then the direction of the resutant R can be written relative to one of the two vectors. The magnitude can be found using the cos formula.
