Sum of magnitudes of two forces acting at a point is 16 ~N . If their resultant is normal to smaller force, and has a magnitude 8 ~N , then forces are
Options
- A6 ~N , 10 ~N
- B8 ~N , 8 ~N
- C4 ~N , 12 ~N
- D2 ~N , 14 ~N
Correct answer
A. 6 ~N , 10 ~N
Step-by-step solution
(16-x)^2=8^2+x^2 aligned 256+x^2-32 x & =64+x^2 32 x & =192 x & = 192 32 =6 aligned Forces 6 ~N , 10 ~N
