If $\mu_{\mathrm{s}}, \mu_{\mathrm{k}}$ and $\mu_{\mathrm{r}}$ are coefficients of static friction, sliding friction and rolling friction, then

Question

If $\mu_{\mathrm{s}}, \mu_{\mathrm{k}}$ and $\mu_{\mathrm{r}}$ are coefficients of static friction, sliding friction and rolling friction, then, $\mu_{\mathrm{s}} < \mu_{\mathrm{k}} < \mu_{\mathrm{f}}$, $\mu_{\mathrm{k}} < \mu_{\mathrm{r}} < \mu_{\mathrm{s}}$, $\mu_{\mathrm{r}} < \mu_{\mathrm{k}} < \mu_{\mathrm{s}}$, $\mu_{\mathrm{r}}=\mu_{\mathrm{k}}=\mu_{\mathrm{s}}$

MARKS App · Accepted Answer

$\mu_{\mathrm{s}} > \mu_{\mathrm{k}} > \mu_{\mathrm{r}}$
