1. Equal 1
2. Less than 1
3. Greater than 1
4. Either equal to or greater than 1

Ans: While ascending a hill Gear Ratio should be “Either equal to or greater than 1”.

Gear Ratio: The ratio between angular velocity of input gear to the angular velocity of output gear. It is represented by R.

Gear Ratio (R) =

$R = \frac{\omega_A}{\omega_B} = \frac{N_B}{N_A}.$
Where w is angular velocity, N is number of teeth on gear
R = \frac{\omega_A}{\omega_B} = \frac{N_B}{N_A}

Velocity:
$v = r_A \omega_A = r_B \omega_B, \!$  —- r is radius of gear.
