question 112

Multiple Choice

A trough is filled with a liquid of density $855 \mathrm {~kg} / \mathrm { m } ^ { 3 }$ . The ends of the trough are equilateral triangles with sides $8 \mathrm {~m}$ long and vertex at the bottom. Find the hydrostatic force on one end of the trough.

• A) \(8.36 \times 10 ^ { 5 } \mathrm {~N}\)
• B) \(5.36 \times 10 ^ { 5 } \mathrm {~N}\)
• C) \(6.36 \times 10 ^ { 5 } \mathrm {~N}\)
• D) \(7.36 \times 10 ^ { 5 } \mathrm {~N}\)
• E) \(4.36 \times 10 ^ { 5 } \mathrm {~N}\)
