If the question is about pressure force then given answer is true. But in question only pressure is there. So please correct it.

Correct answer is (specific weight * omega^2 * r^2)/4g.

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.
