Question

Resultant of two forces F1 and F2 is F1 and the resultant is at rt angle to the force F1 then the force F2 is equl to?

Answer 1

Answer:

Construct the vector F2 such that the magnitude of the vectors

F1 + F2 = F3  

where F3 has the magnitude F1 and is perpendicular to F1

F1^2 + F1^2 = F2^2

F2 = 2^1/2 F1 and the angle between F2 and F1 is 135 deg
