Question

The centripetal force acting on a stone depends 1,mass
2,velocity
3,radius
Derive the expression for centrepetal force (k=1)

Answer 1

$\huge{\underline{\tt{\red{Answer-}}}}$

• Centripetal force is the force that acting on body in circular path.

• Centripetal force depend upon mass and speed of the body and radius of circular path.

$F \propto m\\F \propto v^2\\F \propto \dfrac{1}{r}$

$F= \dfrac{Kmv^2}{r}$ {k= constant}

• Expression for the centripetal force =

$\boxed{F= \dfrac{mv^2}{r}}$ for K=1
