The water in a bath has a depth that changes from $20.0\,\text{cm}$ at the shallow end to $30.0\,\text{cm}$ at the end with the plug. The density of the water is $1000\,\text{kg m}^{-3}$. Determine the pressure exerted by the water on the plug.
- A$1960\,\text{Pa}$
- B$2450\,\text{Pa}$
- C$2940\,\text{Pa}$
- D$4900\,\text{Pa}$
