Question

Two forces are is the ratio 5:2. The maximum I minimum of their resultants are in the ratio is
(A) 5:2
(B) 2:5
(C) 7:3
(D) 1:7​

Answer 1

Answer:

Let force be F1 and F2 then

maximum resultant = F1+F2

minimum resultant =F1-F2

hence

F1+F2 5

--------= -----

F1-F2 2

2F1+2F2=5F1-5F2

5F2+2F2=5F1-2F1

7F2=3F1

F1. 7

---= ------

F2. 3
