A particle moves in a circular orbit under the action of a central attractive force inversely proportional to the distance $'r'$. The speed of the particle is
Proportional to ${r^2}$
Independent of $r$
Proportional to $r$
Proportional to $1/r$
A particle moves in a circular orbit under the action of a central attractive force inversely proportional to the distance $'r'$. The speed of the particle is
$\frac{{m{v^2}}}{r} \propto \frac{K}{r}$
$⇒$ $v \propto r^o$
i.e. speed of the particle is independent of $r$.
