 Apcivilian said: (Dec 8, 2016) It is A. Please Correct it!

 Rita Singh said: (Dec 14, 2016) I think it should be r2.

 Reddy said: (Dec 16, 2016) If the question is about pressure force then given answer is true. But in question only pressure is there. So please correct it.

 Neeraj said: (Feb 9, 2017) Correct answer is (specific weight * omega^2 * r^2)/4g.

 Arif M K said: (Feb 21, 2017) Check Total Pressure definition. The total pressure is defined as the "force" exerted by a static fluid on a surface (either plane or curved) when the fluid comes in contact with the surface. This force is always normal to the surface.
