Velocity Calculation
To calculate the velocity of the layer of water flowing over a fixed horizontal surface, we can use the formula:
Velocity gradient = dv/dy
Where:
- Velocity gradient = 2 s^-1 (given)
- Distance above the surface = 10 cm = 0.1 m

Calculations
Given that the velocity gradient is 2 s^-1 and the distance above the surface is 0.1 m, we can rearrange the formula to solve for velocity:
dv = velocity gradient * dy
dv = 2 s^-1 * 0.1 m
dv = 0.2 m/s
Therefore, the velocity of the layer of water flowing over the fixed horizontal surface at a distance of 10 cm above the surface is 0.2 m/s.
So, the correct answer is option B) 0.2 m/s.
