- Cmore than that on a flat plateCorrect
- Dsometimes more and sometimes less than that on a flat plate
Solution
Concept
Curved plate
Step-by-step solution
1. A curved plate deflects the jet, giving a bigger momentum change.
Explanation
Force is more than on a flat plate.
Why the other options are wrong
Not less or equal.
