Solution

The correct option is C $\frac{V_{2}}{V_{1}}$
The ratio of the velocity of effort to the velocity of the load is called Velocity Ratio $V . R$ . It is unitless, as it is a ratio of two velocities.
Velocity of effort is $V_{2}$ and velocity of load is $V_{1}$ .

So, Velocity ratio $V . R$ = $\frac{V_{2}}{V_{1}}$
