The force exerted by a jet of water impinging normally on a plate which due to the impact of jet, moves in the direction of jet with a velocity v is
A
$$\frac{{{\text{wa}}\left( {{\text{V}} - {\text{v}}} \right)}}{{2{\text{g}}}}$$
B
$$\frac{{{\text{wa}}\left( {{\text{V}} - {\text{v}}} \right)}}{{\text{g}}}$$
C
$$\frac{{{\text{wa}}{{\left( {{\text{V}} - {\text{v}}} \right)}^2}}}{{2{\text{g}}}}$$
D
$$\frac{{{\text{wa}}{{\left( {{\text{V}} - {\text{v}}} \right)}^2}}}{{\text{g}}}$$
Correct Answer: $$\frac{{{\text{wa}}{{\left( {{\text{V}} - {\text{v}}} \right)}^2}}}{{\text{g}}}$$
