Question

the maximum resultant of concurrent forces is 12 newtons and then minimum resultant is 6 newton .then the magnitude of force is​

Answer 1

Answer:

F1=9;F2=3

Explanation:

maximum force that is F1 + F2 is equal to 12 and F1 - F2 is 6 by solving these two equations we get F1 and F2 as F1 is equal to 9 and F2 is equal to 3

Answer 2

Answer:root(90)

Explanation:Max is A+B=12

And mim is A-B=6

Adding above equations

2A=18

A=9

B=3

Resultent of this two vectors are

Root(9*9+3*3)

Root(90)

If angle is given you can use resultent formula ie

Root(A(square)+b(square)+2abcos@)
