3-2.Motion in Plane
normal
ઘડિયાળના કલાક-કાંટા અને મિનિટ-કાંટાની કોણીય ઝડપનો ગુણોત્તર .......
A$1 : 1$
B$3600 : 1$
C$1 : 12$
D$1 : 24$
Solution
$\,\frac{{{\omega _1}}}{{{\omega _2}}}\,\, = \,\,\frac{{\frac{{2\pi }}{{{T_1}}}}}{{\frac{{2\pi }}{{{T_2}}}}}\,\, = \,\,\frac{{{T_2}}}{{{T_1}}}\,\,\,\,\,\,$
$\therefore \,\,\,\frac{{{\omega _1}}}{{{\omega _2}}}\,\, = \,\,\frac{{1hr}}{{12hr}}\,\, = \,\,1:\,\,12$
$\therefore \,\,\,\frac{{{\omega _1}}}{{{\omega _2}}}\,\, = \,\,\frac{{1hr}}{{12hr}}\,\, = \,\,1:\,\,12$
