  • #2
    Tow cars having masses m1 and m2 moves in circles of radii r1 and r2 respectively. If they complete the circle in equal time, the ratio of their angular speed ω1/ω2 is
    (a) m1/m2
    (b) r1/r2
    (c) m1r1/m2/r2
    (d) 1.

    Ans : (d) 1
    Time period (T) is same for both the cars.
    We know that:
    `` \omega \propto \frac{1}{T}``
    `` \,\mathrm{\,So \,},\frac{{\omega }_{1}}{{\omega }_{2}}=1``
