A well 1km deep is filled with a liquid of density 950kg/m(^3) and g = 10m/s(^2), the pressure at the bottom of the well is
-
A.
9.6 × 10(^6)N/m(^2) -
B.
9.5 x 10(^5)N/m(^2) -
C.
9.4 x 10(^6)N/m(^2) -
D.
9.5 x 10(^6)N/m(^2)
Correct Answer: Option A
Explanation
P = Pa + ρgh = (1.00 × 10(^5)) + (950 × 10 × 1000)
P = 10(^5) + (95 × 10(^5)) = 10(^5)(1 + 95) = 96 × 10(^5)
P = 9.6 × 10(^6) N/m(^2)
