If the depth of water in a well is 10 m, what is the pressure exerted by it on the
bottom of the well? (Use g = 10 m/s)
[Ans: 10 N/m]

Respuesta :

Answer:

Let d be the density of the water  (1000 kg / m^3   eq to 1 gm / cm^3)

P = d g h     for the pressure due to a column at the bottom of the column.

P = 1000 kg / m^3 * 10 m/s^2 * 10 m = 10^5 kg / m * s^2 = 10^5 N/m
