A 1.8-m-diameter and 3.6-m-long cylindrical container contains a fluid with a specific gravity of 0.73. The container is positioned vertically and is full of the fluid. Disregarding atmospheric pressure, the hydrostatic force acting on the top and bottom surfaces of this container, respectively, are

(a) 0 kN, 65.6 kN 

(b) 65.6 kN, 0 kN 

(c) 65.6 kN, 65.6 kN

(d) 25.5 kN, 0 kN 

(e) 0 kN, 25.5 kN
