Sum of magnitude of two forces is 25 ~N . The resultant of these forces is normal to the smaller force and has a magnitude of 10 ~N . Then the two forces are
Options
- A14.5 ~N , 10.5 ~N
- B16 ~N , 9 ~N
- C13 ~N , 12 ~N
- D20 ~N , 5 ~N
Correct answer
A. 14.5 ~N , 10.5 ~N
Step-by-step solution
Sum of two forces F₁+F₂=25 Resultant of these forces (10)^2=F₁^2+F₂^2+2 F₁ F₂ Since, resultant is normal to the smaller force F₁+F₂ =0 From Eqs. (i), (ii) and (iii), we get gathered F₁=14.5 ~N F₂=10.5 ~N gathered
