  • Three forces are acting on a particle that has a mass of <img alt="m" src=

Three forces F, f , and \ Kare acting on a particle that has a mass of m kg; Where f and K forces are mutually perpendicular to each other; in this state, the particle is at static and now  F force is removed; the acceleration of the particle is 

Option: 1

\frac{F}{m}


Option: 2

\frac{f}{m}


Option: 3

F+ \frac{f}{m}

 


Option: 4

\frac{K}{m}

When f \ and \ K forces are perpendicular to each other that means                          F=\sqrt{f^{2}+K^{2}} and  F=f+K

Now F force is removed so the resultant force of f \ \ and \ \ K   will move the body with the same amount of force which is equal to  F 

Therefore acceleration =  \frac{F}{m}\: \: \: \: \: \: (Force = mass * acceleration)
