Solution

The correct option is B $N 4 < N_{2} < N_{3} < N_{1}$
$Speed of the wheel \propto \frac{1}{No.of teeth}$

$∴ N_{4} < N_{2} < N_{3} < N_{1}$

In a simple gear train in shown in figure below, the absolute speeds of different wheels, when wheel 4 is the driver.

The correct option is B N4<N2<N3<N1Speed of the wheel∝1No.of teeth ∴N4<N2<N3<N1

The correct option is B $N 4 < N_{2} < N_{3} < N_{1}$
$Speed of the wheel \propto \frac{1}{No.of teeth}$

$∴ N_{4} < N_{2} < N_{3} < N_{1}$
