Question

In $60$ sec the tip of seconds hand travels a distance $2 \pi \ell$

i.e., $\quad \frac{2 \pi \ell}{60}=1.05$

or $\quad \ell=\frac{60 	imes 1.05

Vedclass · Answer

In $60$ sec the tip of seconds hand travels a distance $2 \pi \ell$

i.e., $\quad \frac{2 \pi \ell}{60}=1.05$

or $\quad \ell=\frac{60 	imes 1.05 	imes 7}{2 	imes 22}=\frac{63 	imes 7}{44}$

$=\frac{441}{44} \cong 10 \mathrm{cm}$

The linear speed of the tip of seconds hand of a wall clock is $1.05\,cm\,s^{-1}.$ The length of the seconds hand is nearly ........ $cm$
