Question

two force are such that the sum of their mannitude is 18 N and their resultant parpendicular to the smaller force and the magnitude of resultant is 12 .then the mangnitude of force are ​

Answer 1

Answer:

Explanation:

Consider two forces F1 & F2 and it's given that |F1|+|F2|=18 and the resultant force i.e., |F1→+F2→|=12

⟹F21−F22F21−(18−F1)2−182−122+36F1=122=122[∵|F1|+|F2|=18]=0

⟹F1=182+12236=13

& F2=18−13=5

⟹F2=5
