A non-uniform flask consists of a lower portion that is a circular cylinder 20 cm in radius and 20 cm high. The upper portion is also a circular cylinder, which is 2 cm in radius and 40 cm high. The flask is filled with water.
Calculate:
A. The total weight of the water in the flask
B. The gauge pressure of the water at the bottom of the flask
C. The force exerted on the base of the flask due to the gauge pressure
